Welcome to General Relativity I !

Announcements will be posted here as necessary.

This is the main website for the UIUC Physics Department graduate course PHYS/ASTR 515 on General Relativity. This one-semester course covers the basics of Einstein's theory, developing the mathematical tools and the underlying physical concepts that lead to black holes, neutron stars, gravitational waves and cosmology. You can find a detailed course description, together with an explanation of the target audience for this class, in the course description and syllabus .

In general, you are allowed to use computer algebra software, like Maple or Mathematica, unless stated otherwise. If you do use computer algebra software, together with your PDF solution, you must provide a well-formatted print of your code and attach it as part of your PDF solution. Under no circumstances are you allowed to use a computer algebra package, such as grTensor or xTensor, to calculate tensorial quantities.


We will mainly use "Spacetime and Geometry" by Sean Carroll. This and additional references for further reading are listed under Textbooks.
