General relativity

How do you represent einstein field equations with levi civita symbol or jacobian determinant? I saw a lot of work that involves this but I dont know how and why.

Besides how is the jacobian determinant related to the levI civita symbol?

"Besides how is the jacobian determinant related to the levI civita symbol?"

This follows from the definition of a determinant. One can express the determinant of any matrix (not just the Jacobian matrix) using the Levi Civita symobol :
