ON THE PATH-INDEPENDENCE OF THE GIRSANOV TRANSFORMATION FOR STOCHASTIC EVOLUTION EQUATIONS WITH JUMPS IN HILBERT SPACES

摘要

Based on a recent result in [13] in this paper, we extend it to stochastic evolution equations with jumps in Hilbert spaces. This is done via Galerkin type finite-dimensional approximations of the infinite-dimensional stochastic evolution equations with jumps in a manner that one could then link the characterisation of the path-independence for finite-dimensional jump type SDEs to that for the infinite-dimensional settings. Our result provides an intrinsic link of infinite-dimensional stochastic evolution equations with jumps to infinite-dimensional (nonlinear) integro-differential equations.
