TOTAL CHROMATIC NUMBER OF FUZZY BISTAR GRAPH & FUZZY HELM GRAPH [PDF]
Fuzzy total chromatic number is the least value of k such that k-fuzzy total coloring exist. In this paper, we discussed the concept of total coloring of graphs to Fuzzy bistar graph and Fuzzy helm graph.

On Pathos Semitotal and Total Block Graph of a Tree [PDF]
The concept of pathos of a graph G was introduced by Harary [2], as a collection of minimum number of line disjoint open paths whose union is G. The path number of a graph G is the number of paths in pathos.

On the Total Set Chromatic Number of Graphs
Given a vertex coloring c of a graph, the neighborhood color set of a vertex is defined to be the set of all of its neighbors’ colors. The coloring c is called a set coloring if any two adjacent vertices have different neighborhood color sets.

On the total and AVD-total coloring of graphs [PDF]
A total coloring of a graph G is an assignment of colors to the vertices and the edges such that (i) no two adjacent vertices receive same color, (ii) no two adjacent edges receive same color, and (iii) if an edge e is incident on a vertex v, then v and e receive different colors. The least number of colors sufficient for a total coloring of graph G is

Graphs whose line graphs are ring graphs
Given a graph H, a path of length at least two is called an H-path if meets H exactly in its ends. A graph G is a ring graph if each block of G which is not a bridge or a vertex can be constructed inductively by starting from a single cycle and then in ...

Total Eccentricity Indices Of A Graph [PDF]
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 ...
