GRAPH theory , *DOMINATING set , *MATHEMATICS - Abstract
Graph theory is a branch of mathematics which is quit rich and interesting. The study of domination is one of the fastest growing area in graph. There are different types of domination such as connected domination, independent domination, total domination, paired domination, secure domination , etc. "The secure dominating set S of a graph G is a dominating set with the property that each vertex u∈V\ S is adjacent to a vertex v∈S such that (S\ v) Uu is a dominating set. The minimum cardinality of such a set is called the secure domination number and denoted by γs(G)". In this paper we discuss about the secure domination for some special graphs.

A teacher, who is the provider of the proven educational knowledge, should be adequately competent in terms of expertise, trust, dedication, positive attitude, effective communication and patient listening. All these attributes can surely be inculcated in pupil teacher but only if the training is provided with maximum commitment, with specified objectives, taking into account the needs of todays' educational scenario and the needs of students. This paper emphasize on the system of training being provided to pre-service Mathematics' teachers, to develop their teaching skills. It includes the use of some creative teaching concepts to increase the interest, level of satisfaction and the outcome of their targeted Mathematics' students. Several studies, researches have shown that the students, who have been studying Mathematics since their childhood, are unable to perform simple calculations and are unable to solve simple numerical problem of their everyday life. This study will conclude with some suggestive facts that pre-service trainees should be trained in a way that other than the prescribed curriculum/syllabus, they should spend time to improve quantitative skills using some innovative techniques in regular class practice. As an example, the inventive methodology will also be discussed. And the second highlight will be the the emphasis on continual and rigorous assessment of the trainees during teaching practice, so that they can resolve the dearth and can go ahead with a handful of approaches to serve the purpose of fruitful teaching and learning.

EUCLIDEAN geometry , *MATHEMATICS - Abstract
Isabelle/HOL is a generic proof assistant. Using an Isabelle/HOL requires insight into procedures as well as into the concepts involved. In addition, the way computer manages the procedures can affect mathematical concepts. We can clearly understand mathematical concepts and can minimize the burden of operation opportunities. "Foundations of Geometry" is a book of mathematics written by Hilbert in 1899. The book is famous as the most rigorous study of the axiom system of Euclidean geometry by axioms and formalism. The purpose of this paper is to complement the axiom system by theorizing a part of the problems in this book. [ABSTRACT FROM AUTHOR]

The aim of this paper is to get an estimation of decay rates to first-order and second-order derivatives of space for large-solutions to 3D compressible magnetohydrodynamic system. While the condition (σ0 − 1, u0, Q0) ∈ L1 ∩ H2 is satisfied via a classical energy method and Fourier splitting method, first-order and second-order derivatives of space for large-solutions tending to 0 by L2-rate (1 + t) − 5 4 are shown. It is a necessary supplement to the result of Gao, Wei, and Yao [Appl. Math. Lett. 102, 106100 (2020)] in which they only obtained an estimation of decay rates to magnetic fields. Meanwhile, compared with the work of Gao, Wei, and Yao [Physica D 406, 132506 (2020)], we find that the appearance of magnetic fields does not have any bad effect on the estimation of decay rates to both the velocity field and density.

Mathematics can be used to introduce and explain events and occurrences that have a firmly rooted foundation of logic. This article is created to explain a simple mathematical trick related to cryptanalysis that has existed and allows us to improve upon it by modifying it with logic derived from computer coding and communications. Using error correction based on Hamming code, it is possible to obtain a value between 0-15 by answering yes or no questions about the provided cards. This paper will also explain how to add more cards to discover even a lie immediately and without error. [ABSTRACT FROM AUTHOR]

In the article "Struggling with physics and mathematics curricula based on the notion of function in the context of the educational reform in Poland" (AIP Conf. Proc. 2152; 2019) we analyzed the phenomenon of the lack of correlation between mathematics and physics teaching in the context of the concept of function. It is now taught the secondary school level of mathematics, but is also needed in the teaching of kinematics at the elementary school level of physics. In this paper, we present the chosen results of a pilot pedagogical remote-teaching experiment to provide a preliminary answer to several research questions on this issue: Does the attempt to integrate mathematics and physics have an impact on the understanding of functional relationships in a physics context? Specifically, does the introduction of a propaedeutic of the concept of function in mathematics lessons have an impact on the understanding and ability of analyzing motion? Similarly, do additional lessons on motion analysis affect the proficiency in representing, reading, and interpreting functional relationships? How do students process information about functional relationships in a physical context presented in a variety of representations? Is an elementary school student's intuitive understanding of the concept of functions enough to understand the analysis of motion in physics? What role do the remote experiments performed during the lesson play in learning new issues related to the concept of function in the context of motion analysis? [ABSTRACT FROM AUTHOR]

Mathematics as self-discipline is regarded to be one of the toughest subjects among students. To make this toughest to simplest, few things need to be cultivated inside you. Study habits are one of those things that have been found very useful in the academic success of a student. It is one key for a pupil to recognize and increase expertise in mathematics. These habits need to targeted and practiced at the early stages. There are higher probabilities that it would be a long-term asset for one. The current paper examined the impact of the study habits of school students on mathematics achievement. A sample of 200 students was chosen using random sampling from Government Senior Secondary Schools in Patiala District, Punjab. Questionnaires have been drawn to accumulate records of students' study habits. Students' outcomes in mathematics had been additionally been collected from their achievement in mathematics. Statistical tools has been used to analyze the data. It was concluded that students with good study habits exhibit higher mathematics achievement than students with low study habits. Besides, the authors also suggest how to develop good study habits among students. [ABSTRACT FROM AUTHOR]

Given a random subspace Hn chosen uniformly in a tensor product of Hilbert spaces Vn ⊗ W, we consider the collection Kn of all singular values of all norm one elements of Hn with respect to the tensor structure. A law of large numbers has been obtained for this random set in the context of W fixed and the dimension of Hn, Vn tending to infinity at the same speed by Belinschi, Collins, and Nechita [Commun. Math. Phys. 341(3), 885–909 (2016)]. In this paper, we provide measure concentration estimates in this context. The probabilistic study of Kn was motivated by important questions in quantum information theory and allowed us to provide the smallest known dimension for the dimension of an ancilla space, allowing for Minimum Output Entropy (MOE) violation. With our estimates, we are able, as an application, to provide actual bounds for the dimension of spaces where the violation of MOE occurs. [ABSTRACT FROM AUTHOR]

MATHEMATICS , *ENGINEERING , *MUSIC teachers , *STUDENT interests - Abstract
Music is an important part of education and most students are ardent fans. However, the students are not necessarily aware of the artistic and technical details it takes to create what they hear. These details are what necessitate music and technology coming together. Part of science, technology, engineering, and math (STEM) education should be to help students appreciate the practical applications that come from each of the entities in STEM, namely, science, technology, engineering, and math. Music provides the connection of these elements with a topic that interests the students and motivates their learning. This paper outlines ways for educators to integrate music with STEM topics and put the "A" in "STEAM" (science, technology, engineering, arts, and math). [ABSTRACT FROM AUTHOR]

For a complete extended b-metric space with continuous mapping satisfying the rational type contractive condition, a distinctive common fixed point theorem is established. Our outcome is the extension of several results available in the literature, from metric space to extended b-metric space. In specific, Dass and Gupta[Indian J. Pure Appl. Math. 6, 1455–1458 (1975)], Jaggi[Indian J. Pure Appl. Math. 8, 223–230 (1977)], Alqahtani et.al.[J. Inequal. Appl. Paper No. 220, 11 pp (2019)] and even the well-known Banach contraction mapping theory are extracted. A proper example is also given in sustenance of it. [ABSTRACT FROM AUTHOR]

In this paper, we have illustrated the construction of a real structure on a fuzzy sphere S * 2 in its spin-1/2 representation. Considering the SU(2) covariant Dirac and chirality operator on S * 2 given by U. C. Watamura and Watamura [Commun. Math. Phys. 183, 365–382 (1997) and Commun. Math. Phys. 212, 395–413 (2000)], we have shown that the real structure is consistent with other spectral data for KO dimension-4 fulfilling the zero order condition, where we find it necessary to enlarge the symmetry group from SO(3) to the full orthogonal group O(3). However, the first order condition is violated, thus paving the way to construct a toy model for an SU(2) gauge theory to capture some features of physics beyond the standard model following Chamseddine et al. (J. High Energy Phys. 2013, 132). [ABSTRACT FROM AUTHOR]

This paper aims at studying the inelastic Boltzmann equation without Grad's angular cutoff assumption, where the well-posedness theory of the Cauchy problem is established for the Maxwellian molecules in a space of probability measure defined by Cannone and Karch [Commun. Pure Appl. Math. 63, 747–778 (2010)] via Fourier transform and the infinite energy solutions are not a priori excluded. The key strategy is to construct a brand new geometric relation of the inelastic collision mechanism to extend the result of Cannone and Karch from moderate singularity of the non-cutoff collision kernels to strong singularity and simultaneously handle more general restitution coefficients. Moreover, we extend the self-similar solution to the Boltzmann equation with infinite energy shown by Bobylev and Cercignani [J. Stat. Phys. 106, 1039–1071 (2002)] to the inelastic case by using a constructive approach, which is also proved to be the large-time asymptotic steady solution with the help of an asymptotic stability result in a certain sense.

MATHEMATICS , *EQUATIONS , *EXPONENTS - Abstract
Whether the three dimensional isentropic compressible Navier–Stokes equations admit weak solutions for arbitrary initial data with adiabatic exponent γ > 1 remains a challenging problem. The only available results under γ > 1 were achieved by either assuming the initial data with small energy due to Hoff [J. Differ. Equations 120(1), 215–254 (1995)] or under the spherically symmetric condition by Jiang and Zhang [Commun. Math. Phys. 215, 559–581 (2001)] and Huang [J. Differ. Equations 262, 1341–1358 (2017)]. In this paper, we establish the existence of weak solutions with higher regularity of the three-dimensional periodic compressible isentropic Navier–Stokes equations in small time for the adiabatic exponent γ > 1 in the presence of vacuum. It can be viewed as a local version of Hoff's work and also extends the result of Desjardins [Commun. Partial Differ. Equations 22(5–6), 977–1008 (1997)] by removing the assumption of γ > 3.

We thank Professor Jordan for his comments[1] on our paper.[2] Indeed, he is right in pointing that when I i tends to infinite and I i tends to infinite, but I i / I i remains finite, Eq. (3) of his comment[1] tends to a wave equation for I u i , if coefficient I i in the last term (non-linear term) is finite. The criticism by Jordan[1] related to the lack of the Joule effect has no relation with our work, because we did not consider any electric flux, but only heat propagation. However, his proposal [Eq. (4) in Ref. [1]] of considering that coefficient I i of the last term is proportional to I i or to I i is interesting and deserves analysis. [Extracted from the article]
