TensoriaCalc tackles (semi-)Riemannian tensor calculus problems encountered in general relativity, cosmology, and field theory. Currently, it calculates geometric objects – Christoffel symbols, the Riemann curvature tensor, Ricci tensor and scalar, etc. – given a metric and the relevant coordinates; and performs basic operations such as covariant derivatives of tensors.
