In this paper, we study a coupled fully hybrid system of (k , Φ) –Hilfer fractional differential equations equipped with non-symmetric (k , Φ) –Riemann-Liouville (RL) integral conditions. To prove the existence and uniqueness results, we use the Krasnoselskii and Perov fixed-point theorems with Lipschitzian matrix in the context of a generalized Banach space (GBS). Moreover, the Ulam–Hyers (UH) stability of the solutions is discussed by using the Urs's method. Finally, an illustrated example is given to confirm the validity of our results.

The aim of this study is to provide a generalization of prime vague Γ -ideals in Γ -rings by introducing non-symmetric 2-absorbing vague weakly complete Γ -ideals of commutative Γ -rings. A novel algebraic structure of a primary vague Γ -ideal of a commutative Γ -ring is presented by 2-absorbing weakly complete primary ideal theory. The approach of non-symmetric 2-absorbing K-vague Γ -ideals of Γ -rings are examined and the relation between a level subset of 2-absorbing vague weakly complete Γ -ideals and 2-absorbing Γ -ideals is given. The image and inverse image of a 2-absorbing vague weakly complete Γ -ideal of a Γ -ring and 2-absorbing K-vague Γ -ideal of a Γ -ring are studied and a 1-1 inclusion-preserving correspondence theorem is given. A vague quotient Γ -ring of R induced by a 2-absorbing vague weakly complete Γ -ideal of a 2-absorbing Γ -ring is characterized, and a diagram is obtained that shows the relationship between these concepts with a 2-absorbing Γ -ideal.

In this paper, we establish several necessary conditions to confirm the uniqueness-existence of solutions to an extended multi-order finite-term fractional differential equation with double-order integral boundary conditions with respect to asymmetric operators by relying on the Banach's fixed-point criterion. We validate our study by implementing two numerical schemes to handle some Riemann–Liouville fractional boundary value problems and obtain approximate series solutions that converge to the exact ones. In particular, we present several examples that illustrate the closeness of the approximate solutions to the exact solutions. [ABSTRACT FROM AUTHOR]

In this research study, we establish some necessary conditions to check the uniqueness-existence of solutions for a general multi-term ψ -fractional differential equation via generalized ψ -integral boundary conditions with respect to the generalized asymmetric operators. To arrive at such purpose, we utilize a procedure based on the fixed-point theory. We follow our study by suggesting two numerical algorithms called the Dafterdar-Gejji and Jafari method (DGJIM) and the Adomian decomposition method (ADM) techniques in which a series of approximate solutions converge to the exact ones of the given ψ -RLFBVP and the equivalent ψ -integral equation. To emphasize for the compatibility and the effectiveness of these numerical algorithms, we end this investigation by providing some examples showing the behavior of the exact solution of the existing ψ -RLFBVP compared with the approximate ones caused by DGJIM and ADM techniques graphically.

This study deals with a novel class of mean-type inequalities by employing fractional calculus and convexity theory. The high correlation between symmetry and convexity increases its significance. In this paper, we first establish an identity that is crucial in investigating fractional mean inequalities. Then, we establish the main results involving the error estimation of the Hermite–Hadamard inequality for composite convex functions via a generalized Riemann-type fractional integral. Such results are verified by choosing certain composite functions. These results give well-known examples in special cases. The main consequences can generalize many known inequalities that exist in other studies. [ABSTRACT FROM AUTHOR]

Drugs have always been one of the most important concerns of families and government officials at all times, and they have caused irreparable damage to the health of young people. Given the importance of this great challenge, this article discusses a non-symmetric fractal-fractional order ice-smoking mathematical model for the existence results, numerical results, and stability analysis. For the existence of the solution of the given ice-smoking model, successive iterative sequences are defined. The uniqueness of the solution Hyers–Ulam (HU) stability is established with the help of the existing definitions and theorems in functional analysis. By the utilization of two-step Lagrange polynomials, we provide numerical solutions and provide a comparative numerical analysis for different values of the fractional order and fractal order. The numerical simulations show the applicability of the scheme and future prediction and the effects of fractal-fractional orders simultaneously. [ABSTRACT FROM AUTHOR]

In this article, we provide constraints for the sum by employing a generalized modified form of fractional integrals of Riemann-type via convex functions. The mean fractional inequalities for functions with convex absolute value derivatives are discovered. Hermite–Hadamard-type fractional inequalities for a symmetric convex function are explored. These results are achieved using a fresh and innovative methodology for the modified form of generalized fractional integrals. Some applications for the results explored in the paper are briefly reviewed. [ABSTRACT FROM AUTHOR]

A nonlinear quantum boundary value problem (q-FBVP) formulated in the sense of quantum Caputo derivative, with fractional q-integro-difference conditions along with its fractional quantum-difference inclusion q-BVP are investigated in this research. To prove the solutions' existence for these quantum systems, we rely on the notions such as the condensing functions and approximate endpoint criterion (AEPC). Two numerical examples are provided to apply and validate our main results in this research work. [ABSTRACT FROM AUTHOR]
