摘要
We establish a representation formula for the transition probability density of a diffusion perturbed by a vector field, which takes a form of Cameron-Martin's formula for pinned diffusions. As an application, by carefully estimating the mixed moments of a Gaussian process, we deduce explicit, strong lower and upper estimates for the transition probability function of Brownian motion with drift of linear growth.
