报告摘要：

Since the establishment, black hole thermodynamics has been extensively studied. Especially, different phase structures and critical phenomena have been disclosed in the extended phase space. In this talk, I will show how to introduce the topological study to the black hole thermodynamics. The results show that different types critical points can be well distinguished by their topological number. Moreover, local stable or unstable black hole solution can be endowed with a positive or negative topological charge. Summing them will give an universal constant underlying the black hole thermodynamics, which may have potential applicant in understanding the quantum gravity.
