ON 2-PATH INVARIANT SIGNED GRAPHS
A signed graph S is a graph called the underlying graph of S denoted by in which each line x carries a value called its sign. The function is called a signing of G. The set of positive lines of S is denoted by whence and we call the line set of S. The notion of n-path graphs which was introduced by Escalante et al. [2] was extended to signed graph theory by Gill and Patwardhan [1]. In this paper, we discuss on a different version of n-path invariant signed graphs and establish some results on particular classes of n-path signed graphs, namely, 2-path signed graphs.
