摘要 (Abstract)：

The quasinormal modes are an important class of characteristic physical quantities of black holes, and one straightforward way to compute them is to use the connection formulae. The connection formulae, however, in general are difficult to derive. In this talk, we provide supportive evidence to (i) the connection formulae obtained from 2d CFT reproduce the correct QNMs for differential equation with only regular singularities; (ii) the connection formulae for irregular singularities may be obtained by taking the collision limit appropriately.
