Time-inhomogeneous polynomial processes
- MathematicsStochastic Analysis and Applications
- 2019
Abstract In this work, we develop polynomial processes where the coefficients of the process may depend on time. A full characterization of this model class is given by means of their semimartingale…

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…
Affine processes are regular

We show that stochastically continuous, time-homogeneous affine processes on the canonical state space $${\mathbb{R}_{\geq 0}^m \times \mathbb{R}^n}$$ are always regular. In the paper of Duffie et…
Path Properties and Regularity of Affine Processes on General State Spaces

- 2013
We provide a new proof for regularity of affine processes on general state spaces by methods from the theory of Markovian semimartingales. On the way to this result we also show that the definition…

Let A be a pseudo-differential operator with negative definite symbol q . In this paper we establish a sufficient condition such that the well-posedness of the ( A, C ∞ c ( R d )) martingale problem…

It is proved that the joint process of the Markov chain and the conditionally affine part is a process with an affine structure on an enlarged state space, conditionally on the starting state of theMarkov chain.
Feller Processes Generated by Pseudo-Differential Operators: On the Hausdorff Dimension of Their Sample Paths
- Mathematics
- 1998
Let {Xt}t≥0 be a Feller process generated by a pseudo-differential operator whose symbol satisfiesÇ∈∝n|q(Ç,ξ)|≤c(1=ψ)(ξ)) for some fixed continuous negative definite function ψ(ξ). The Hausdorff…
