Theorem tsmsxp 23306
Description: Write a sum over a two-dimensional region as a double sum. This infinite group sum version of gsumxp 19577 is also known as Fubini's theorem. The converse is not necessarily true without additional assumptions. See tsmsxplem1 23304 for the main proof; this part mostly sets up the local assumptions.
