For α = 0, our results improve some previously known bounds. Also, we discuss similar properties of the compressed zero-divisor graph. We also obtain lower bounds for $D_{\alpha}S(G)$ in terms of clique number and independence number of the graph $G$ and characterize the extremal graphs for some cases. Graph Theory gives us, both an easy way to pictorially represent many major mathematical results, and insights into the deep theories behind them. Much of graph theory is concerned with the study of simple graphs. %���� Since Fe, For a simple graph $G(V,E)$ with $n$ vertices, $m$ edges, vertex set $V(G)=\{v_1, v_2, \dots, v_n\}$ and edge set $E(G)=\{e_1, e_2,\dots, e_m\}$, the adjacency matrix $A=(a_{ij})$ of $G$ is a $(0, 1)$-square matrix of order $n$ whose $(i,j)$-entry is equal to 1 if $v_i$ is adjacent to $v_j$ and equal to 0, otherwise. finite state morphology, using finite state transducers) are common in the a nalysis of l anguage as a gr aph. For a commutative ring R with non-zero zero-divisor set Z∗(R), the zero-divisor graph of R is Γ(R) with vertex set Z∗(R), where two distinct vertices x and y are adjacent if and only if xy=0.

Let$\partial_{1}(G)\geq \partial_{2}(G)\geq \dots \geq \partial_{n}(G)$be the eigenvalues of$D_{\alpha}(G)$and let$D_{\alpha}S(G)=\partial_{1}(G)-\partial_{n}(G)$be the generalized distance spectral spread of the graph$G$. download 1 … APPLICATIONS OF GRAPH THEORY – PIRZADA AND DHARWADKER 23 The automorphism group of a graph G is the group of all permutations p of the vertices of G with the property that p(x)p(y) is an edge of G if and only if xy is an edge of G. A group H of permutations acting on a set V is called semi-regular if for each x V, the stabilizer H x = {h H: xh = x} consists of the identity only, where A graph isomorphic to its complement is called self-complementary. Finally, when G is abelian we obtain better bounds in both cases. Visualizations are a powerful way to simplify and interpret the underlying patterns in data. >> Ganie and S.

For α = 0, our results improve some previously known bounds. Also, we discuss similar properties of the compressed zero-divisor graph. We also obtain lower bounds for$D_{\alpha}S(G)$in terms of clique number and independence number of the graph$G$and characterize the extremal graphs for some cases. Graph Theory gives us, both an easy way to pictorially represent many major mathematical results, and insights into the deep theories behind them. Much of graph theory is concerned with the study of simple graphs. %���� Since Fe, For a simple graph$G(V,E)$with$n$vertices,$m$edges, vertex set$V(G)=\{v_1, v_2, \dots, v_n\}$and edge set$E(G)=\{e_1, e_2,\dots, e_m\}$, the adjacency matrix$A=(a_{ij})$of$G$is a$(0, 1)$-square matrix of order$n$whose$(i,j)$-entry is equal to 1 if$v_i$is adjacent to$v_j$and equal to 0, otherwise. finite state morphology, using finite state transducers) are common in the a nalysis of l anguage as a gr aph.
