Calculating Stress Energy Tensor for Rotating Bodies

Click For Summary
SUMMARY

The discussion focuses on calculating the stress-energy tensor for rotating bodies, specifically in the context of general relativity. The stress-energy tensor, denoted as T^{ab}, includes pressure components for indices (a,b) in the range of 1 to 3. The user seeks clarification on the significance of the first row and column of the tensor, indicating a lack of familiarity with the stress tensor derived from the stress-energy tensor. Reference is made to Nikolaos Stergioulas' work on rotating stars in relativity for further insights.

PREREQUISITES
  • Understanding of general relativity concepts
  • Familiarity with tensor calculus
  • Knowledge of the stress-energy tensor and its components
  • Basic principles of rotating bodies in physics
NEXT STEPS
  • Study the derivation of the stress-energy tensor in general relativity
  • Explore the implications of rotating stars as detailed in Nikolaos Stergioulas' research
  • Learn about the significance of each component of the stress-energy tensor
  • Review the mathematical formulation of tensors in physics
USEFUL FOR

This discussion is beneficial for physicists, students of general relativity, and researchers interested in the dynamics of rotating bodies and their associated stress-energy tensors.

Hello, can someone explain to me how to calculate the stress energy tensor. If we remove the first row and column, we get get the stress tensor, which I am not familiar with, or am I missing something here? But what about the components of the first column and row. What I know so far is that T^{ab}=\texttt{pressure for $ (a,b) \in (1,3)$}. Everything else is pitch black. I am interested in the stress-energy tensor of a rotating body.
Any feedback will be appreciated.

The http://en.wikipedia.org/wiki/Stress-energy_tensor" has a figure that describes each component of the tensor.

Maybe Eq 11 or thereabouts.
