Theorem tsmsxp 22763
Description: Write a sum over a two-dimensional region as a double sum. This infinite group sum version of gsumxp 19096 is also known as Fubini's theorem. The converse is not necessarily true without additional assumptions. See tsmsxplem1 22761 for the main proof; this part mostly sets up the local assumptions.
