In this paper, we consider homogeneous quasideviation means generated by real functions (defined on (0, ∞)) which are concave around the point 1 and possess certain upper estimates near 0 and ∞. It turns out that their concave envelopes can be completely determined. Using this description, we establish su˚cient conditions for the Hardy property of the homogeneous quasideviation mean and we also furnish an upper estimates for its Hardy constant.

This paper focuses on introducing and examining the class of generalized strongly n-polynomial convex functions. Relationships between these functions and other types of convex functions are explored. The Hermite–Hadamard inequality is established for generalized strongly n-polynomial convex functions. Additionally, new integral inequalities of Hermite–Hadamard type are derived for this class of functions using the Hölder–İşcan integral inequality. The results obtained in this paper are compared with those known in the literature, demonstrating the superiority of the new results. Finally, some applications for special means are provided.

Subsequently, we present an illustrative example complete with graphical representations to validate our theoretical findings. The paper concludes with practical applications of these inequalities, demonstrating their potential impact across various fields of mathematical and applied sciences. [ABSTRACT FROM AUTHOR]

These inequalities encompass several novel findings and refinements of established results. To enhance readers' comprehension, we offer illustrative examples that highlight appropriate choices of multiplicatively convex mappings along with graphical representations. Finally, we demonstrate the applicability of our results to special means of real numbers within the realm of multiplicative calculus. [ABSTRACT FROM AUTHOR]

Moreover, several Bullen-type inequalities are established for twice-differentiable functions. More precisely, conformable fractional integrals are used to derive such inequalities. Furthermore, sundry significant inequalities are obtained by taking advantage of the convexity, Hölder inequality, and power-mean inequality. Finally, we provide our results by using special cases of obtained theorems. [ABSTRACT FROM AUTHOR]

In this paper, we first introduce four new generalized quantum integrals of two variables functions which are called T q -integrals. We also give some examples of each of these given integrals. Then we establish corresponding T q -Hermite–Hadamard type inequalities for co-ordinated convex functions.

In this paper, by considering the identity established by Luo et al. in [C. Luo, T.-S. Du, M. Kunt and Y. Zhang, Certain new bounds considering the weighted Simpson-like type inequality and applications, J. Inequal. Appl. 2018 2018, Paper No. 332] and under the assumption of the quasi-convexity of the first derivative, we establish some new error estimates of the Simpson-like type inequalities. We also discuss the case where the first derivative satisfies the Hölder condition. At the end, we provide some applications to special means. The obtained results represent a continuation of the above-mentioned paper. [ABSTRACT FROM AUTHOR]

In this paper, we develop a concept of a logarithmically superquadratic function. Such a class of functions is defined via superquadratic functions. We first establish some new properties of superquadratic functions. In particular, we derive the corresponding superadditivity relation and its reverse, as well as the external form of the Jensen inequality and its reverse. Then, as a direct consequence of the established results, we obtain the corresponding properties for logarithmically superquadratic functions. Further, we show that logarithmically superquadratic functions with values greater than or equal to one are convex and logarithmically superadditive. In particular, we also obtain the corresponding refinement of the Jensen inequality in a product form. Finally, we give a variant of the Jensen operator inequality for logarithmically superquadratic functions. [ABSTRACT FROM AUTHOR]

In this paper, we obtain several Adams-type inequalities with logarithmic weights on the unit ball B in R n , where n ≥ 3 . Firstly, we show that for any β ∈ 0 , 1 , the following critical Adams' inequality sup u ∈ W 0 , r 2 , n 2 (B , ω) , u ω ≤ 1 ∫ B exp α u n n - 2 1 - β d x < ∞ holds if and only if α ≤ α β = n n - 2 n 2 n V n 2 n - 2 1 - β 1 - β 1 1 - β , where V n = π n 2 Γ n 2 + 1 is the volume of the unit ball B in R n , W 0 , r 2 , n 2 (B , ω) is the radial weighted Sobolev space under the norm u ω = ∫ B Δ u n 2 ω x d x 2 n with ω (x) = log 1 x β (n 2 - 1) or ω (x) = log e x β (n 2 - 1) . Secondly, we prove the following two supercritical Adams' inequalities sup u ∈ W 0 , r 2 , n 2 (B , ω) , u ω ≤ 1 ∫ B exp α β + x m u n n - 2 1 - β d x < ∞ and sup u ∈ W 0 , r 2 , n 2 (B , ω) , u ω ≤ 1 ∫ B exp α β u n n - 2 1 - β + x m d x < ∞ , where m is some positive number. Moreover, we prove the existence of extremals for these Adams-type inequalities. [ABSTRACT FROM AUTHOR]

Integral inequalities with generalized convexity play an important role in both applied and theoretical mathematics. The theory of integral inequalities is currently one of the most rapidly developing areas of mathematics due to its wide range of applications. In this paper, we study the concept of higher-order strongly exponentially convex functions and establish a new Hermite–Hadamard inequality for the class of strongly exponentially convex functions of higher order. Further, we derive some new integral inequalities for Riemann–Liouville fractional integrals via higher-order strongly exponentially convex functions. These findings include several well-known results and newly obtained results as special cases. We believe that the results presented in this paper are novel and will be beneficial in encouraging future research in this field. [ABSTRACT FROM AUTHOR]

In this paper we give some new power-type refinements and reverses of the weighted arithmetic–geometric mean inequality. Our result is a remarkable generalization of the one due to Furuichi (J Math Inequal 5(1):21–31, 2011), Manasrah and Kittaneh (J Math Anal Appl 361(1):262–269, 2010, Linear Multilinear Algebra 59(9):1031–1037, 2011). When the power is a positive integer number, our result is also a refinement of a very recent generalization established by Ighachane et al. (Math Inequal Appl 23(3):1079–1085, 2020) for this inequality. As an application, we provide some generalized inequalities for determinants of positive definite matrices. [ABSTRACT FROM AUTHOR]

This paper adopts different optimization algorithms such as Genetic Algorithm (GA) and Particle Swarm Optimization Algorithm (PSO-Algorithm) to train Back-Propagation (BP) neural networks, fits the Chinese, the Czech, Slovak, Hungarian, and Polish gross domestic product (GDP) growth model (from 1995 to 2020) and makes short-term simulation predictions. We use the PSO-Algorithm and GA with strong global search ability to optimize the weights and thresholds of the network, combine them with the BP neural network, and apply the resulting Particle Swarm Optimization Back-Propagation (PSO-BP) combined model or Genetic-Algorithm Back-Propagation (GA-BP) combined model to allow the network to achieve fast convergence. Besides, we also compare the above two hybrid models with standard multivariate regression model and BP neural network with different initialization methods like normal uniform and Xavier for fitting and short-term simulation predictions. Finally, we obtain the excellent results that all the above models have achieved a good fitting effect and PSO-BP combined model on the whole has a smaller error than others in predicting GDP values. Through the technology of PSO-BP and GA-BP, we have a clearer understanding of the five countries gross domestic product growth trends, which is conducive to the government to make reasonable decisions on the economic development.

In this paper, we extend the Minkowski integral inequality on time scales by Δ Δ -integral and the inverse Minkowski inequality over the set of constant sign functions. We get similar results by replacing Δ Δ -integral with Δ ∇ , ∇ Δ and ∇ ∇ -integrals. For application, we give another proof of the Hardy inequality on time scales according to the Minkowski inequality. [ABSTRACT FROM AUTHOR]

This paper aims to extend the application of the Ostrowski inequality, a crucial tool for figuring out the error bounds of various numerical quadrature rules, including Simpson's, trapezoidal, and midpoint rules. Specifically, we develop a more comprehensive class of Ostrowski-type inequalities by utilizing the weighted version of Riemann–Liouville (RL) fractional integrals on an increasing function. We apply our findings to estimate the error bounds of Hadamard-type inequalities. Our results are more comprehensive, since we obtain the results of the existing literatures as particular cases for certain parameter values. This research motivates researchers to apply this concept to other fractional operators. [ABSTRACT FROM AUTHOR]

This paper proves an equality for the case of differentiable convex functions including the conformable fractional integrals. By using this equality, we establish several parameterized inequalities with the help of the conformable fractional integrals. Several inequalities are obtained by taking advantage of the convexity, the Hölder inequality, and the power mean inequality. Furthermore, we present previously achieved results and new results by using special cases of the obtained theorems. [ABSTRACT FROM AUTHOR]

Based on the uncertainty theory, Liu [B. Liu, Some research problems in uncertainty theory, J. Uncertain Syst. 3 2009, 1, 3–10] introduced an uncertain integral for applying uncertain differential equation, finance, control, filtering and dynamical systems. Since uncertain integrals are the important content of uncertainty theory, this paper explores an approach of the relationship between uncertain integrals by the well-known Chebyshev-type inequality. Also, we propose the concept of an uncertain fractional integral which is generalized version of an uncertain integral. The definition of a strong comonotonic uncertain process and some new properties of the uncertain integral were presented in [C. You and N. Xiang, Some properties of uncertain integral, Iran. J. Fuzzy Syst. 15 2018, 2, 133–142]. Based on the strong comonotonic uncertain process, as an application, we provide Chebyshev's inequality for a fractional uncertain integral and an uncertain integral. [ABSTRACT FROM AUTHOR]

In this paper, we introduced the concept of multiplicatively p-convex functions and established Hermite-Hadamard type integral inequalities in the setting of multiplicative calculus for this newly created class of functions. We also gave integral inequalities of Hermite-Hadamard type for product and quotient of multiplicatively p-convex functions. Furthermore, we obtained novel multiplicative integral-based inequalities for the product and quotient of convex and multiplicatively p-convex functions. Additionally, we derived certain upper limits for this new class of functions. The findings we proved are generalizations of the results in the literature. The results obtained in this study may inspire further research in various scientific areas. [ABSTRACT FROM AUTHOR]

In this paper, the improvements in the estimations of some entropies are of our interest. These improvements can also be done sequentially. We find some new and refined bounds for the Tsallis entropy, Tsallis quasilinear entropy, and Tsallis quasilinear divergence. The estimations for the Tsallis entropy are provided with respect to the Shannon entropy and Rényi entropy. We obtain some alternative refined bounds for the Tsallis relative operator entropy and we establish the significant refined relation between the Tsallis relative operator entropy and the generalized relative operator entropy.

Many of the fastest known algorithms to compute π involve generalized hypergeometric series, such as the Ramanujan–Sato series. In this paper, we investigate the rates of convergence for several such series and we give asymptotic expansions for the error of finite approximation. For example, when using the first n terms of the Chudnovskys' series, we obtain the finite approximation π n ≈ π . It is known that the truncation error satisfies | π n - π | ≈ 53360 - 3 n. In this paper, we prove that the asymptotic expansion for the truncation error in the Chudnovskys' series is π n - π = 53360 - 3 n 106 720 10 005 π 1 672 209 n exp A 1 n + A 2 n 2 + δ n n 3 , with 0.006 907 < δ n < 0.008 429 and the exact rational values of A 1 and A 2 : A 1 = - 1 781 843 197 433 7 456 754 505 816 , A 2 = - 1 080 096 011 925 710 088 395 3 475 199 235 000 451 148 614 116. Thus we demonstrate how to establish precise error bounds for the approximations for π obtained through Ramanujan-like series for 1 / π . [ABSTRACT FROM AUTHOR]

Yager has introduced the q-rung orthopair fuzzy set (q-ROFS), which is the most significant generalization of the Pythagorean fuzzy set (PFS). The q-rung orthopair adjusts in the needed boundary range when the q rung value increases. As a result, the q-ROFS input range is more adaptable, resilient, and appropriate than the intuitionistic fuzzy set and PFS. In this paper, we proposed new entropy measure for q-rung orthopair fuzzy set and it is being proved that the proposed entropy measure follows all the requirements of an entropy measure for q-ROFs. Numerical example depicts the efficiency of the proposed entropy measure. Furthermore, in the present paper entropy weighted method is applied to compute weights vector where partial information is used for criteria weights. Then, a new decision-making method using inferior ratio method based on proposed entropy measure is put forward. The working of the proposed multi-criteria decision-making model is explained through a numerical example. At last, a detailed comparison of the proposed model with certain current approaches is given, which demonstrates that the proposed decision model is more effective and beneficial than existing methodologies.
