[:pb]Título: Matrix Method for Quasinormal Modes

Palestrante: Kai Lin (IFQ)

Data/Local: Quarta, 12 de Abril de 2017 / 17h50 / sala 14 – Prédio do IFQ

Descrição:  “We proposed the Matrix method to study the quasinormal modes of black holes. The method involves discretizing the master field equation and expressing it in form of a homogeneous system of linear algebraic equations. The resulting homogeneous matrix equation furnishes a non-standard eigenvalue problem, which can be then solved numerically to obtain the quasinormal frequencies. A key feature of the present approach is that the discretization of the wave function and its derivatives are made to be independent of any specific metric through coordinate transformation. In many cases, it can be carried out beforehand which in turn improves the efficiency and facilitates the numerical implementation.”
