WebSep 4, 2024 · To justify the derivation above, let's discuss how to define the Lie derivative of a connection. While a connection is not a tensor, the space of all connections form an affine space as the difference between two connections is a tensor. Given a diffeomorphism φ: M → M and a connection ∇ on T M, we can get a new connection by the formula. WebThe part of the covariant derivative that keeps track of changes arising from change of basis is the Christoffel symbols. They encode how much the basis vectors change as we move along the direction of the basis vectors themselves. How is this useful in General Relativity?
