One of the best known and widely used is the Zagreb topological index of a graph G M_1(G) introduced in 1972 by I. Gutman and N. Trinajstic and is defined as the sum of the squares of the degrees of all vertices of G, M_{1}(G)=\sum\limits_{v\in V(G)} {d_{v}}^2 (or =\sum\limits_{e=uv\in E(G)} {d_{u}+d_{v}}, where d_{u} denotes the degree (number of first neighbors) of vertex u in G. Also, the Second Zagreb index M_2(G) is equal to M_{2}(G)=\sum\limits_{e=uv\in E(G)} {d_{u} \times d_{v}}. In this paper, we focus on the structure of molecular graph Circumcoronene Series of Benzenoid H_{k} (k>1) and its line graph L(H_{k}) and counting First Zagreb index and Second Zagreb index of L(H_{k}).

Computationally effective numerical methods, Euler’s method is given meticulously while Euler’s Modified method presented here gives a better exactness. No higher order derivatives are required to be tabulated. Drawbacks and advantages of the methods are discussed here and the results obtained by them have been compared. The idea behind this paper is to illustrate the facts of implementing a small number of steps of Euler's modified method, in addition , how to apply built-in functions available in C++ [1]. Firstly, we use Euler methods to bring in the fundamental thoughts linked with initial value problems (IVP) and then later on, we apply the Euler’s Modified method associated to the built-in C++ . The purpose of this paper is to go from textbook formula on ODE to production software. Keywords: Euler’s Method, Euler’s Modified Method, C++, ODE.

Vertex set V(G) is labeled arbitrary by positive integers and E(e) denote the edge label such that it is the sum of labels of vertices incident with edge e. The labeling is said to be lucky edge labeling if the edge E(G) is a proper coloring of G, that is, if we have E(e_{1})\neq E(e_{2}) whenever e_{1} and e_{2} are adjacent edges. The least integer k for which a graph G has a lucky edge labeling from the set \{1, 2,\dots, k\} is the lucky number of G denoted by \eta(G). A graph which admits lucky edge labeling is the lucky edge labeled graph. In this paper, we proved that complete graph K_{n}, tadpole graph T_{m, n} and rectangular book B_{p}^{4} are lucky edge labeled graphs.

Abstract: Let $G=(V, E)$ be a graph. The vertex polynomial of the graph $G=(V,E)$ is defined as $V(G,x)=\sum\limits_{k=0}^{\Delta(G)}{v_{k}x^{k}}$, where $\Delta (G)=\max\{d(v)/v\in V\}$ and $v_{k}$ is the number of vertices of degree $k$. The adjacent vertex sum polynomial is defined as $S(G, x)=\sum\limits_{i=o}^{\Delta(G)}{n_{\Delta(G)-i}x^{\alpha_{\Delta (G)-i}}}$, where $n_{\Delta(G)-i}$ is the sum of the number of adjacent vertices of all the vertices of degree $\Delta(G)-i$ and $\alpha_{\Delta(G)-i}$ is the sum of the degree of adjacent vertices of all the vertices of degree $\Delta(G)-i$. In this paper we seek to find the vertex polynomial and the adjacent vertex sum polynomial for the splitting graph of Perfect factograph and the splitting graph of Integral Perfect factograph.

Keywords: Perfect factograph, Integral Perfect factograph, Vertex polynomial, Adjacent vertex sum polynomial, Splitting graph.
