On the inverse signed total domination number in graphs

In this paper, we study the inverse signed total domination number in graphs and present new sharp lower and upper bounds on this parameter. For example by making use of the classic theorem of Turán (1941), we present a sharp upper bound on \(K_{r+1}\)-free graphs for \(r\geq 2\). Also, we bound thi...
