This paper studies the asymptotics of the Brownian integrals with paths restricted to a bounded domain of Rν , when the domain is dilated to infinity. The framework is that of the Bose- Einstein statistics with paths observed within random time intervals which are integer multiplies of some fixed β > 0. The three first terms of the asymptotics are found explicitly via the functional integrals. In the case of a gas of interacting Brownian loops an expression for the volume term of the asymptotics of the log-partition function is found and the correction term is proved by order to be the boundary area of the domain.

Abstract
This paper studies the asymptotics of the Brownian integrals with paths restricted to a bounded domain of Rν , when the domain is dilated to infinity. The framework is that of the Bose- Einstein statistics with paths observed within random time intervals which are integer multiplies of some fixed β > 0. The three first terms of the asymptotics are found explicitly via the functional integrals. In the case of a gas of interacting Brownian loops an expression for the volume term of the asymptotics of the log-partition function is found and the correction term is proved by order to be the boundary area of the domain.File in questo prodotto:
