Comparison theorems on resistance distances and Kirchhoff indices of S, T -isomers. Let G be a connected graph. An edge cut of G is a set of edges that, if removed from G, disconnects the graph; and a minimal edge cut is an edge cut none of whose nonempty proper subsets is an edge cut. If e is an edge of G, we denote by G − e …
