We study discretizations of polynomial processes using finite state Markov processes satisfying suitable moment matching conditions. The states of these Markov processes together with their transition probabilities can be interpreted as Markov cubature rules. The polynomial property allows us to study such rules using algebraic techniques. Markov cubature rules aid the tractability of path-dependent tasks such as American option pricing in models where the underlying factors are polynomial… 
Abstract polynomial processes.
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
Cubature Method for Stochastic Volterra Integral Equations
TLDR
The cubature measure is introduced for Stochastic Volterra Integral Equations, and construct it explicitly in some special cases, including a long memory stochastic volatility model.
Polynomial Jump-Diffusion Models
TLDR
A large class of novel financial asset pricing models that are based on polynomial jump-diffusions are introduced, including a generic method for option pricing based on moment expansions.

Quantization goes polynomial
TLDR
Recursive marginal quantization has a high convergence rate in numerical approximation of stochastic volatility option pricing models and it is shown that this convergence rate is higher in classical quantization models than in the discrete-time models.

Polynomial processes and their applications to mathematical finance
We introduce a class of Markov processes, called m-polynomial, for which the calculation of (mixed) moments up to order m only requires the computation of matrix exponentials. This class contains
