Bounds on Sum Number in Graphs
A simple undirected graph G is called a sum graph if there is a labeling L of the vertices of G into distinct positive integers such that any two vertices u and v of G are adjacent if and only if there is a vertex w with label L(w) = L(u) + L(v). The sum number (H) of a graph H = (V; E) is the least integer r such that graph G consisting of H and r isolated vertices is a sum graph. It is clear ...

A simple undirected graph G is called a sum graph if there is a labeling L of the vertices of G into distinct positive integers such that any two vertices u and v of G are adjacent if and only if there is a vertex w with label L(w) = L(u) + L(v).

متن کاملSome new bounds on the general sum--connectivity index
Let $G=(V,E)$ be a simple connectedgraph with $n$ vertices, $m$ edges and sequence of vertex degrees$d_1 ge d_2 ge cdots ge d_n>0$, $d_i=d(v_i)$, where $v_iin V$. With $isim j$ we denote adjacency ofvertices $v_i$ and $v_j$. The generalsum--connectivity index of graph is defined as $chi_{alpha}(G)=sum_{isim j}(d_i+d_j)^{alpha}$, where $alpha$ is an arbitrary real<b...
متن کاملBounds for the general sum-connectivity index of composite graphs
The general sum-connectivity index is a molecular descriptor defined as [Formula: see text], where [Formula: see text] denotes the degree of a vertex [Formula: see text], and α is a real number. Let X be a graph; then let [Formula: see text] be the graph obtained from X by adding a new vertex [Formula: see text] corresponding to each edge of X and joining [Formula: see text] to the end vertices...
متن کاملSome lower bounds for the $L$-intersection number of graphs
For a set of non-negative integers~$L$, the $L$-intersection number of a graph is the smallest number~$l$ for which there is an assignment of subsets $A_v subseteq {1,dots, l}$ to vertices $v$, such that every two vertices $u,v$ are adjacent if and only if $|A_u cap A_v|in L$. The bipartite $L$-intersection number is defined similarly when the conditions are considered only for the ver...
