New Concepts of Picture Fuzzy Graphs with Application
Mathematics, 2019 The picture fuzzy set is an efficient mathematical model to deal with uncertain real life problems, in which a intuitionistic fuzzy set may fail to reveal satisfactory results.

ESAIM: Proceedings and Surveys, 2014 Let f:X → X be a continuous map defined from a topological space X into itself. We discuss the problem of analyzing and computing explicitly the set Per(fp) of periods of the p-th iterate ...

On well-covered direct products
Discussiones Mathematicae Graph Theory, 2020 A graph $G$ is well-covered if all maximal independent sets of $G$ have the same cardinality. In 1992 Topp and Volkmann investigated the structure of well-covered graphs that have nontrivial factorizations with respect to some of the standard graph products.

Hyperbolicity of Direct Products of Graphs [PDF]
Symmetry, 2018 It is well-known that the different products of graphs are some of the more symmetric classes of graphs. Since we are interested in hyperbolicity, it is interesting to study this property in products of graphs. Some previous works characterize the hyperbolicity of several types of product graphs (Cartesian, strong, join, corona and lexicographic ...

Union of Distance Magic Graphs
Discussiones Mathematicae Graph Theory, 2017 A distance magic labeling of a graph G = (V,E) with |V | = n is a bijection ℓ from V to the set {1, . . . , n} such that the weight w(x) = ∑y∈NG(x) ℓ(y) of every vertex x ∈ V is equal to the same element μ, called the magic constant.

Direct product of Neutrosophic INK Algebras [PDF]
Neutrosophic Sets and Systems, 2020 In this paper, first we define the notion direct product of neutrosophic sets in INK-algebras, neutrosophic set, neutrosophic INK-ideals, neutrosophic closed INK-ideals and direct product of neutrosophic INK-ideals in INK-algebras. We prove some theorems

Rainbow eulerian multidigraphs and the product of cycles [PDF]
Discrete Mathematics & Theoretical Computer Science, 2016 An arc colored eulerian multidigraph with $l$ colors is rainbow eulerian if there is an eulerian circuit in which a sequence of $l$ colors repeats. The digraph product that refers the title was introduced by Figueroa-Centeno et al. as follows: let $D$ be

Permanents of Direct Products [PDF]
Proceedings of the American Mathematical Society, 1966 It is well known that if \(A\) and \(B\) are \(n\) and \(m\)-square matrices, respectively, then \(\det(A\otimes B) = (\det A)^m (\det B)^n\), where \(A\otimes B)\) is the tensor or direct product of \(A\) and \(B\). This implies \[ \vert\det(A\otimes B)\vert^2 = (\det(AA^*))^m (\det(B^*B))^n, \] where \(A^*\) is the conjugate transpose of \(A\).

Two dimentional lattice vibrations from direct product representations of symmetry groups
International Journal of Mathematics and Mathematical Sciences, 1983 Arrangements of point masses and ideal harmonic springs are used to model two dimensional crystals. First, the Born cyclic condition is applied to a double chain composed of coupled linear lattices to obtain a cylindrical arrangement.
