What's strange is the integral is defined in a purely formal way for generalized functions, so the usual change of variable formula doesn't exist, but I think the author has chosen to write this to look like the usual change of variable formula. It's somewhat irrelevant here because that term is always 1. I think for a noncompact group where the determinant was not always 1, you would need to put a determinant term in the first formula as well, to match this one. | |
