Abstract

{x(t) − x(s)} are the increments of the three dimensional Brownian motion over the intervals [s, t]. (Formula Presented). Qα,T is defined as the measure with Radon–Nikodym derivative [Z(T, α)]−1 exp [αF(T, ω)] with respect to Brownian Motion, Z(α, T) being the normalization constant Z(T, α) = E[exp [αF(T, ω)]]. We are interested in the existence of the Polaron measure Qα =limT→∞Qα,T, the validity of central limit theorem for (Formula Presented) under Qα,T as well as Qα and the behavior of Qα for large α.
