On total directed graphs of non-commutative rings
For a non-commutative ring , the left total directed graph of is a directed graph with vertex set as and for the vertices and , is adjacent to if and only if there is a non-zero which is different from and , such that is a left zero-divisor of .

Smarandache-Zagreb Index on Three Graph Operators [PDF]
Many researchers have studied several operators on a connected graph in which one make an attempt on subdivision of its edges. In this paper, we show how the Zagreb indices, a particular case of Smarandache-Zagreb index of a graph changes with these ...

On the genus of some total graphs
Let be a commutative ring with a proper ideal . A generalization of total graph is introduced and investigated. It is the (undirected) graph with all elements of as vertices, that two distinct vertices are adjacent if and only if where for some and is a ...

Total Eccentricity Indices Of A Graph
We have defined and evaluated total eccentricity indices of polyhex nanotubes TUAC6(p, q) and TUZC6(p, q). In thispaper, we compute First Total Eccentricity Index, Second Total Eccentricity Index, First Multiplicative Total Eccentricity Index, Second ...

For a (molecular) graph, the Wiener index, hyper-Wiener index and degree distance index are defined as $$W(G)= \sum_{\{u,v\}\subseteq V(G)}d_G(u,v),$$ $$WW(G)=W(G)+\sum_{\{u,v\}\subseteq V(G)} d_{G}(u,v)^2,$$ and $$DD(G)=\sum_{\{u,v\}\subseteq V(G)}d_G(u,

F index of graphs based on four new operations related to the strong product
For a molecular graph, the first Zagreb index of a graph is equal to the sum of squares of the vertex degrees of the graph and the forgotten topological index (F-index) of a graph is defined as the sum of cubes of the vertex degrees of the graph.

Complete bipartite graph is a totally irregular total graph
A graph G is called a totally irregular total k-graph if it has a totally irregular total k-labeling λ : V ∪ E→ 1, 2, ... , k, that is a total labeling such that for any pair of different vertices x and y of G, their weights wt(x) and wt(y) are distinct,
