WebJun 1, 2024 · We characterize the Markovian and affine structure of the Volterra Heston model in terms of an infinite-dimensional adjusted forward process and specify its state space. More precisely, we show that it satisfies a stochastic partial differential equation and displays an exponentially-affine characteristic functional.

In particular, their characteristic functions can be solved by ordinary differential or integral equations, so-called Riccati equations.

WebIn the case of affine Volterra models, we derive explicit solutions to this BSDE in terms of multidimensional Riccati--Volterra equations. This framework includes multivariate rough Heston models and extends the results of Han and Wong [ Appl. Math. Optim. (2024)].
