Inverting Signed Graphs

SIAM Journal on Algebraic Discrete Methods, 1984
This paper addresses the question of determining the class of rectangular matrices having a given signed graph as a signed row or column graph. We also determine equivalent conditions on a given pair of signed graphs in order for them to be the signed row and column graphs of some rectangular matrix.

Connected signed graphs L-cospectral to signed ∞-graphs

Linear and Multilinear Algebra, 2018
A signed graph is a pair Γ=(G,σ), where G=(V(G),E(G)) is a graph and σ:E(G)→{+1,−1} is the sign function on the edges of G.

C-consistent line signed graphs of Cayley signed graphs

Journal of Interdisciplinary Mathematics, 2023
The Cayley graph, signed graph and line graph are well known in the literature. Now, our focus is to study line signed graphs of Cayley signed graphs. In this paper, we have characterized the Cayley sets and generating sets for which line signed graphs of Cayley signed graphs are canonically consistent(C-consistent).
