A single number that can be used to characterize some property of the graph of a molecular is called a topological index for that graph. In this paper, we compute several topological indices of linear [n]-anthracene, V-anthracene nanotube and nanotori: multiplicative Zagreb, multiplicative hyper-Zagreb, multiplicative sum connectivity, multiplicative product connectivity, general multiplicative Zagreb, multiplicative ABC and multiplicative GA indices

The b-Chromatic number of a graph is the maximum number of k of colors that can be used to color the vertices of G. Let us consider the color classes for differentline graphs, where every line graphs with i has a representative (the color i dominating vertex) that is able to communicate with all the other line graphs. Further we investigate the b-chromatic number for certain triangular graphs such as triangular snake graphs, triangular fan graphs, triangular cylindrical graphs andwe also generalized some of the results based on these graphs.

The aim of the present paper is to study the unsteady flow of a visco-elastic Rivlin-Ericksen (1955) type fluid through porous medium in a long uniform rectangular duct under the influence of an impulsive pressure gradient acting at the central part of a section. The analytical expressions for velocity profile and flux have been determined by the application of transform technique. Some particular cases have been discussed in detail. The results for the flow of ordinary viscous fluid have also been deduced by taking parameter

A edge dominating set F of a graph G = (V , E) is an accurate edge dominating set, if < E F > has no edge dominating set of cardinality | F | . The accurate edge domination number (G) ae is the minimum cardinality of an accurate edge dominating set. We study the graph theoretic properties of (G) ae and its exact values for some standard graphs. The relation between (G) ae with other parameters are also investigated

In this paper, on tricomplex representation methods of a matrix trace inequality is introduced. A matrix trace inequality for positive semi definite Hermitian matrices A and B, 0<tr (A*B)n<(trA)n *(trB)n is established, where n is an integer. The above inequality improves the result given by Yang (J Math. Anal. Appl. 250 (2000), 372-374

In this paper we introduce the new class of functions called binary supra -irresolute functions and deals with the concrete examples. The purpose of the present note is to introduce a strong form of binary supra continuity called binary supra strongly -irresolute which is stronger than binary supra -irresolute. Basic and some comparitive properties of these fuctions are studied in this paper

In this paper, the authors study the various properties enjoyed by strict and dominant fuzzy graphs introduced in3, by the authors. The usual operations on these fuzzy graphs are not extendable. For the first time such deviant nature is analysed
