Acharya, B. Devadas Connectedness and acyclicity of the transposed square of a graph. (English) Zbl 0597.05058 Indian J. Pure Appl. Math. 17, 756-759 (1986). Summary: J. Plonka [Graph theory, Proc. Conf., Lagow/Pol. 1981, Lect. Notes Math. 1018, 170-178 (1983; Zbl 0529.05054)] introduced the notion of transposed square of a given graph, possibly with loops. In this paper, we characterize connected (acyclic) graphs, without loops, whose transposed squares are connected (acyclic).
