报告摘要Trees play an important role in the study of graphs. In this talk, I will introduce some known results and open problems on determining the number of spanning trees in a connected graph and on its relation with some other parameters of graphs. The talk will also include some open problems related to the independence polynomials of trees and the chromatic symmetrical functions of trees.
