摘要:
The computation of two-point resistances in electrical networks is a classical problem in electric circuit theory which is related to the enumeration of spanning trees of graphs. It is well known that the mesh-star transformation plays an important role in the electrical networks. In this talk, we will first introduce some of known results on electrical networks and enumeration of spanning trees of graphs in the content of combinatorics, and then we present the so-called CMG-BS transformation in resistance and in spanning tree versions. Using this local transformation, we obtain some results on the resistance distances and spanning trees.This is joint work with Sujing Cheng and Wuxian Chen.
