Abstract

U ovom radu ćemo proučavati metode za pronalaženje frekvencija kvazinormalnih modova crnih rupa. Prvo smo našli izraze za frekvencije kvazinormalnih modova pri međudjelovanju masenih skalarnih polja i BTZ crne rupe analitičkim putem te smo ih usporedili sa rješenjima Kerrovih crnih rupa. Nadalje smo puluanalitičkim i numeričkim metodama proučavali međudjelovanje bezmasenih skalarnih polja i Reissner- Nordströmove crne rupe.

Abstract (english)

In this paper, we will study methods for finding the frequencies of quasinormal modes of black holes. First, we found analytical expressions for the frequencies of quasinormal modes in the interaction of massive scalar fields and BTZ black holes, and compared them with solutions of Kerr black holes. Futhermore, we studied the interaction of massless scalar fields and the Reissner-Nordström's black hole by semianalytic and numerical methods.
