## Abstract The path number of a graph __G__, denoted __p(G)__, is the minimum number of edgeβdisjoint paths covering the edges of __G.__ LovΓ‘sz has proved that if __G__ has __u__ odd vertices and __g__ even vertices, then __p(G)__ β€ 1/2 __u__ + __g__ β 1 β€ __n__ β 1, where __n__ is the total numbe
An upper bound for total colouring of graphs, Discrete Mathematics 111 (1993) 3899392. We give an upper bound on the number of colours required to extend a given vertex colouring of a graph to a total colouring. This shows that for any simple graph there is a total colouring using at most :d + 3 co
