The stochastic Keller--Segel system in critical spaces
Jae-Hwan Choi, Ankit Kumar, Andrea Pitrone +2
The paper analyzes stochastic Keller–Segel equations on a d‑dimensional torus within scaling‑critical Besov spaces, establishing local well‑posedness and showing that, for sufficie…

An existence and uniqueness theory to stochastic partial differential equations involving pseudo-differential operators driven by space-time white noise
Jae-Hwan Choi, Ildoo Kim
In this paper, we aim to develop a new weak formulation that ensures well-posedness for a broad range of stochastic partial differential equations with pseudo-differential operator…
