Total Colourings - A survey
The smallest integer needed for the assignment of colors to the elements
so that the coloring is proper (vertices and edges) is called the total
chromatic number of a graph. Vizing and Behzed conjectured that the total
coloring can be done using at most colors, where is
the maximum degree of .
It is not settled even for planar graphs. In this paper we give a survey on
total coloring of graphs.Comment: 23 pages, 3 figures 1 tabl
