SUMMARY
The discussion focuses on the transformation laws for tensors under general coordinate transformations, specifically for a tensor of type (0,1) and a tensor of type (2,1). The transformation formula for a (0,1) tensor is given as V_a' = ∂x^k/∂{x'}^a V_k, which describes how the tensor V_k transforms when changing coordinates. The second formula, x_a' = x_a'(x_b), represents the coordinate transformation itself. The first formula is derived from the second, confirming their interrelation in tensor transformation.
