# Multilinear processes in Banach space

@inproceedings{Benth2018MultilinearPI, title={Multilinear processes in Banach space}, author={Fred Espen Benth and Nils Detering and Paul Kruhner}, year={2018} }

A process (X(t))t≥0 taking values in R d is called a polynomial process if for every polynomial p of degree n on R, there exists another polynomial q of degree at most n such that E[p(X(t)) |Fs] = q(X(s)) for any t ≥ s ≥ 0. Based on multilinear maps we extend the notion of polynomial processes to a general Banach space B, to form a class of multilinear processes. If B is a Banach algebra and one restricts to multilinear maps being products, our notion of a multilinear process coincides with a…

We suggest a novel approach to polynomial processes solely based on a polynomial action operator. With this approach, we can analyse such processes on general state spaces, going far beyond Banach…

Measure-valued affine and polynomial diffusions

It is shown the so-called moment formula, i.e. a representation of the conditional marginal moments via a system of finite dimensional linear PDEs, and characterize the corresponding infinitesimal generators and obtain a representation analogous to polynomial diffusions on R+, in cases where their domain is large enough.
