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. WebWe introduce affine Volterra processes, defined as solutions of certain stochastic …

WebMay 24, 2024 · Affine processes have proved particularly convenient for financial modelling, typically giving rise to models with tractable formulae for the values of financial claims; the perennially popular Heston model [ 16] is just one (and perhaps the most famous) example of such a model. WebDec 1, 2024 · We extend recent results on affine Volterra processes to the inhomogeneous case. This includes moment bounds of solutions of Volterra equations driven by a Brownian motion with an inhomogeneous... bear lake days

Theirasymptotic propertieswerealso investigated thanks to Malli-avin calculus [BGS21] and the stochastic sewing lemma [HL20]. As usual with fractional sto-chastic integrals however, these frameworks do not accommodate for the highly irregular paths WebAug 1, 2024 · In general, affine processes build an important class of stochastic processes because despite being non-Gaussian they still exhibit some analytic tractability. In particular, their characteristic functions can be solved by ordinary differential or integral equations, so-called Riccati equations.
