Second quantisation for skew convolution products of infinitely divisible measures

Suppose $λ_1$ and $λ_2$ are infinitely divisible Radon measures on real Banach spaces $E_1$ and $E_2$, respectively and let $T:E_{1} \rightarrow E_{2}$ be a Borel measurable mapping so that $T(λ_1) * ρ= λ_2$ for some Radon probability measure $ρ$ on $E_{2}$. Extending previous results for the Gaussian and the Poissonian case, we study the problem of representing the `transition operator' $P_{T}:L^{p}(E_{2}, λ_{2}) \rightarrow L^{p}(E_{1}, λ_{1})$ given by $P_{T}f(x) = \int_{E_{2}}f(T(x) + y)dρ(y)$ as the second quantisation of a contraction operator acting between suitably chosen `reproducing kernel Hilbert spaces' associated with $λ_1$ and $λ_2$.
