Markov property for systems driven by the Brownian sheet
Nacira Agram, Bernt Øksendal, Frank Proske +1
We study stochastic systems driven by a Brownian sheet and formulate a Markov property adapted to their two-parameter structure. For time-space homogeneous Itô sheets, the future e…
Optimal Stopping for Systems Driven by the Brownian Sheet
Nacira Agram, Bernt Oksendal, Frank Proske +1
We investigate optimal stopping problems for systems driven by the Brownian sheet. Our analysis is divided into two parts. In the first part we derive explicit solutions to two opt…
Fokker-Planck equations for conditional McKean-Vlasov systems driven by Brownian sheets
Nacira Agram, Bernt Øksendal, Frank Proske +1
We investigate conditional McKean-Vlasov equations driven by time-space white noise, motivated by the propagation of chaos in an N-particle system with space-time Ornstein-Uhlenbec…
A Kalman filter for linear systems driven by time-space Brownian sheet
Nacira Agram, Bernt Øksendal, Frank Proske +1
We study a linear filtering problem where the signal and observation processes are described as solutions of linear stochastic differential equations driven by time-space Brownian…
Fokker-Planck equation for McKean-Vlasov SPDEs driven by time-space Brownian sheet
Nacira Agram, Bernt Oksendal, Frank Proske +1
In this paper, we consider a McKean-Vlasov (mean-field) stochastic partial differential equations (SPDEs) driven by a Brownian sheet. We study the propagation of chaos for a space-…
Long-time behaviors of some stochastic differential equations driven by Lévy noise
I. Orlovskyi, F. Proske, O. Tymoshenko
Using key tools such as Itô formula for general semi-martingales, moments estimates for Lévy-type stochastic integrals and properties of regular varying functions we find condition…
