Where can I found an expressionfor the shear stress tensor in GR with some explanation about it?
Thanks

Sorry but I've never heard about such a thing. There's a stress-energy-momentum tensor. Is that what you're referring to?blue_sky said:Where can I found an expressionfor the shear stress tensor in GR with some explanation about it?

The shear stress energy tensor in general relativity is a mathematical object used to describe the distribution of energy and momentum in spacetime. It is a 4x4 matrix that contains information about the stress and shear forces present in a given region of spacetime.
The shear stress energy tensor is one of the terms in Einstein's field equations, which describe the curvature of spacetime in the presence of matter and energy. It represents the contribution of matter and energy to the overall curvature of spacetime.
The shear stress energy tensor is important in understanding the dynamics of matter and energy in the universe. It allows us to calculate the effects of gravity on matter and energy, and to make predictions about the behavior of objects in spacetime.
The shear stress energy tensor is calculated using the stress-energy-momentum tensor, which takes into account not only the distribution of matter and energy, but also the flow of energy and momentum. It is a complex mathematical process that involves integrating the contributions of all matter and energy in a given region of spacetime.
The shear stress energy tensor has many practical applications in the field of astrophysics and cosmology. It is used to study the behavior of matter and energy in extreme environments, such as black holes and neutron stars. It also helps us to understand the expansion of the universe and the formation of large-scale structures, such as galaxies and galaxy clusters.
