Global existence of dissipative solutions to the Camassa--Holm equation with transport noise
Galimberti, Luca; Holden, Helge; Karlsen, Kenneth Aksel Hvistendahl; Pang, Ho Cheung (Peer reviewed; Journal article, 2023)We consider a nonlinear stochastic partial differential equation (SPDE) that takes the form of the Camassa–Holm equation perturbed by a convective, position-dependent, noise term. We establish the first global-in-time ... -
Global well-posedness of the viscous Camassa–Holm equation with gradient noise
Holden, Helge; Karlsen, Kenneth Aksel Hvistendahl; Pang, Ho Cheung (Peer reviewed; Journal article, 2022)We analyse a nonlinear stochastic partial differential equation that corresponds to a viscous shallow water equation (of the Camassa–Holm type) perturbed by a convective, position-dependent noise term. We establish the ... -
The Hunter-Saxton equation with noise
Holden, Helge; Karlsen, Kenneth Hvistendahl; Pang, Ho Cheung (Peer reviewed; Journal article, 2021)In this paper we develop an existence theory for the Cauchy problem to the stochastic Hunter–Saxton equation (1.1), and prove several properties of the blow-up of its solutions. An important part of the paper is the ... -

Strong solutions of a stochastic differential equation with irregular random drift
Karlsen, Kenneth Aksel Hvistendahl; Holden, Helge; Pang, Ho Cheung (Peer reviewed; Journal article, 2022)We present a well-posedness result for strong solutions of one-dimensional stochastic differential equations (SDEs) of the form where the drift coefficient is random and irregular, with a weak derivative satisfying for ...
