# Thread: Invariance of physical laws (Tensors)

1. ## Invariance of physical laws (Tensors)

The invariance of physical laws to a coordinate change suggests a symmetry group structure. Can the operations of cordinate transformation be written as group operations? What is the group?

2. ## Re: Invariance of physical laws (Tensors)

First, that looks like a homework problem. Second, the resulting group depends upon what the transformations are.
