We prove a Girsanov theorem for the combination of a Brownian motion onR+and a Poisson random measure onR+x[-1,1]dunder random anticipating transformations of paths and configurations. The factorization of the density function via Carleman—Fredholm determinants and divergence operators appears as an extension of the martingale factorization in the adapted jump case.
