Introduction to General Relativity

This course provides an introduction to Einstein’s theory of gravity, known as General Relativity. The initial part focuses on the mathematical tools in field theory, differential geometry, and tensor calculus necessary to formulate the theory and arrive at the Einstein equations. The remainder of the course explores specific solutions to the Einstein equations and their properties, including black holes, gravitational waves, and cosmological spacetimes. A series of compulsory exercises accompanies the course. This course is a recommended precursor to the „Advanced General Relativity“ course typically offered in the following semester.

Advanced General Relativity

The course focuses on dynamic solutions to Einstein’s field equations relevant to both cosmology and astrophysics. It covers solutions for expanding universes, rotating compact objects—such as black holes and neutron stars—and the collapse leading to black hole formation. A series of compulsory exercises accompanies the course. Building on topics from the recommended precursor, „Introduction to General Relativity“, this course provides the essential tools for research in General Relativity.
