Abstract
It is well known that the integral identity conjecture is of prime importance in Kontsevich-Soibelman's theory of motivic Donaldson-Thomas invariants for non-commutative Calabi-Yau threfolds. In this article we consider its numerical version and make it a complete demonstration in the case where the potential is a polynomial and the ground field is algebraically closed. The foundamental tool is the Berkovich spaces whose crucial point is how to use the comparison theorem for nearby cycles as well as the K\"{u}nneth isomorphism for cohomology with compact support.
