We study a class of 'nonpoissonian' transformations of the configuration space and the corresponding transformations of the Poisson measure. For some class of Poisson measures we find conditions which are sufficient for the transformed measure (which in general is nonpoissonian) to be absolutely continuous with respect to the initial Poisson measure and get the expression for the corresponding RadonNikodym derivative. To solve this problem we use a distributional approach to Poisson multiple stochastic integrals.Mathematics Subject Classifications (1991) 28C20 · 60H05 · 60G57.
