Abstract
- The index of a signed graph is the largest eigenvalue of its adjacency matrix. Let Un,k,4 be the set of all signed complete graphs of order n whose negative edges induce a unicyclic graph of order k and girth at least 4. In this paper, we identify the signed graphs achieving the maximum index in the class Un,k,4. [ABSTRACT FROM AUTHOR]
