Abstract
We derive a simple calculation rule for Aoyama-Tamra's prescription for path integral with degenerated potential minima. Nonperturbative corrections due to the restricted functional space (fundamental region) can systematically be computed with this rule. It becomes manifest that the prescription might give Borel summable series for finite temperature (or volume) system with quantum tunneling, while the advantage is lost at zero temperature (or infinite volume) limit.
