Skolem Odd Difference Mean Graphs
In this paper we define a new labeling called skolem odd difference mean labeling and investigate skolem odd difference meanness of some standard graphs. Let G = (V,E) be a graph with p vertices and q edges. G is said be skolem odd difference mean if there exists a function f : V (G) → {0, 1, 2, 3, . . . , p + 3q − 3} satisfying f is 1−1 and the induced map f : E(G) → {1, 3, 5, . . . , 2q−1} de...
متن کامل$k$-Total difference cordial graphs
Let $G$ be a graph. Let $f:V(G)to{0,1,2, ldots, k-1}$ be a map where $k in mathbb{N}$ and $k>1$. For each edge $uv$, assign the label $left|f(u)-f(v)right|$. $f$ is called a $k$-total difference cordial labeling of $G$ if $left|t_{df}(i)-t_{df}(j)right|leq 1$, $i,j in {0,1,2, ldots, k-1}$ where $t_{df}(x)$ denotes the total number of vertices and the edges labeled with $x$.A graph with admits a...
متن کاملDifference graphs
Intersection and measured intersection graphs are quite common in the literature. In this paper we introduce the analogous concept of measured difference graphs: Given an arbitrary hypergraph H = {H1, ..., Hn}, let us associate to it a graph on vertex set [n] = {1, 2, ..., n} in which (i, j) is an edge iff the corresponding sets Hi and Hj are “sufficiently different”. More precisely, given an i...
متن کاملDifference Graphs
In the conceptual structures community, much effort and attention has been focused on determining areas of commonality between two or more conceptual graphs. Less attention has been paid to another aspect of comparison, namely, what is different between two or more graphs. This paper explores a technique called difference graphs for determining and representing the differences between two graph...
