Description

Black hole geometries are curious solutions of the general theory of relativity. In this module we shall study such black hole geometries from both a classical and a quantum perspective. The module will effectively have two parts. In the first half we shall discuss different exact but `time-independent’ black hole solutions, their causal structures, and symmetries, finally leading to the thermodynamic nature of these black holes.

The second half of the module will be more fluid in nature and its structure will depend on how the first part goes. Here, we attempt to construct dynamical but approximate black hole solutions, we might study black holes in semi-classical gravity, leading to the topic of Hawking radiation, and we might contemplate the information paradox.
