Abstract:

The Y-index of a graph is defined by the sum of four of degrees of the vertices of a graph. Among the all topological indices the Zagreb indices have been used more considerably than any other topological indices in chemical literature. The concept of Corona Product is a recent inclusion to mathematical vocabulary. One of the most significant graph operations is the corona product of several generic and specific graphs, which is one of the most well-known graph products. In this study, we derive some explicit formulations of several corona product types, including subdivision-vertex corona, su

Abstract:

Dominator coloring is a fascinating type of proper coloring where vertices are assigned colors so that every vertex in the graph is within the closed neighborhood of at least one vertex from each color class. The smallest number of colors needed for a dominator coloring is called the dominator chromatic number. In this paper, a new graph product called the closed extended neighborhood corona of two graphs is introduced and its dominator chromatic number for any pair of connected graphs is determined. Also, the dominator chromatic numbers for the extended corona of a path with any graph and a c

Abstract:

Every t-dynamic proper n-coloring of a graph G describes a shadow allocation of any (n,t+1)-threshold secret sharing scheme based on G, so that, after just one round of communication, each participant can either reconstruct the secret, or obtain a different shadow from each one of his/her neighbors. Thus, for just one round of communication, this scheme is fair if and only if the threshold is either less than or equal to the minimum degree of G, or greater than or equal to its maximum degree. Despite that the dynamic coloring problem has widely been dealt with in the literature, a comprehensiv

Let G=(V(G),E(G)) be a simple graph. A neighborhood connected k-fair dominating set (nckfd-set) is a dominating set S subset V(G) such that |N(u) intersection S|=k for every u is an element of V(G)\S and the induced subgraph of S is connected. In this paper, we introduce and invistigate the notion of neighborhood connected k-fair domination in graphs. We also characterize such dominating sets in the join, corona, lexicographic and cartesians products of graphs and determine the exact value or sharp bounds of their corresponding neighborhood connected k-fair domination number.

Abstract:

A dominator coloring of a graph G is a proper coloring of G in which each vertex of the graph dominates every vertex of some color class. The dominator chromatic number of G is the minimum number of color classes in a dominator coloring of G. When operation on graphs is performed on classes of graphs result from the new class of graphs are obtained. The neighborhood corona is one such operation on graphs, having interesting applications as well. In this paper we study this operation on certain graph classes and discuss the bounds in terms of domination number and dominator chromatic number.

A distance antimagic graph is a graph G admitting a bijection f:V(G)→{1,2,…,|V(G)|} such that for two distinct vertices x and y, ω(x)≠ω(y), where ω(x)=∑y∈N(x)f(y), for N(x) the open neighborhood of x.

Abstract:

We discuss application of contemporary methods of the theory of dynamical systems with regular and chaotic hyperbolic dynamics to investigation of topological structure of magnetic ﬁelds in conducting media. For substantial classes of magnetic ﬁelds, we consider well-known physical models allowing us to reduce investigation of such ﬁelds to study of vector ﬁelds and Morse-Smale diﬀeomorphisms as well as diﬀeomorphisms with nontrivial basic sets satisfying the A axiom introduced by Smale. For the point-charge magnetic ﬁeld model, we consider the problem of separator playing an important role in

COVID-19, a novel corona virus has affected the life of each and every individual worldwide. Nepal being the neighborhood country of china, though, we had a late case detection. But, since the month of July this virus has spread in an alarming manner in Nepal. Nepal being one of the developing countries, we lack in equipments, manpower resources and also in treatment centers. Looking into the devastating scenario of Covid 19 in China, Italy, New York, Brazil and our neighboring countries like India, Pakistan and Bangladesh is scary. We wondered how we were going to handle this pandemic if simi

Introduction. The fast-moving consumer goods (FMCG) industry is one of the basic ones for the existence of society and almost the first industry that directly felt the impact of the corona crisis and needed prompt adaptation. Problem. China has been named the undisputed leader in economic growth over the past few years, so analyzing the impact of the pandemic on the underlying sectors of the economy is an important aspect to study this country. The aim of the article is to determine the state and trends of the impact of COVID-19 on FMCG and service sectors in China. Methods. The research was c

Abstract:

Light bending is one of the classical tests of general relativity and is a crucial aspect to be taken into account for accurate assessments of photon propagation. In particular, high-precision astrometry can constrain theoretical models of gravitation in the weak field limit applicable to the Sun neighborhood. We propose a concept for experimental determination of the light deflection close to the Sun in the 10−7 to 10−8 range, in a modern rendition of the 1919 experiment by Dyson, Eddington and Davidson, using formation flying to generate an artificial long-lasting eclipse.

In this process, only the area of Daya-dong, near Mount Suri, has remained a rural area and has maintained its traditional village until now. The new urban area was replaced by the indigenous people who had local cultural resources due to the new influx, and in the process, Gunpo City lost its cultural base using local cultural resources.
