Title: Well-posedness for fractional Hardy-Hénon parabolic equations with fractional Brownian noise
(Submitted on 18 Apr 2024)
Abstract: We investigate the fractional Hardy-H\'enon equation with fractional Brownian noise $$ \partial_t u(t)+(-\Delta)^{\theta/2} u(t)=|x|^{-\gamma} |u(t)|^{p-1}u(t)+\mu \partial_t B^H(t), $$ where $\theta>0$, $p>1$, $\gamma\geq 0$, $\mu \in\mathbb{R}$, and the random forcing $B^H$ is the fractional Brownian motion defined on some complete probability space $(\Omega, \mathcal{F}, \mathbb{P})$ with Hurst parameter $H\in (0,1)$. We obtain the local existence and uniqueness of mild solutions under tailored conditions on the parameters of the equation.
