Consider a perfect fluid in a static, circularly symmetric (2+1)-dimensional spacetime.
Derive the analogue of the Tolman-Oppenheimer-Volkov (TOV) equation for (2+1)-dimensions
The Attempt at a Solution
Okay. I'm trying to think this through. I've replaced the phi component of the schwarzchild metric with some random variable because we only need circular symmetry. but where do I go from here?
