Well-Posedness for Cauchy Problems with Singular Time-Measurable Pseudo-Differential Operators in Quasi-decreasing Weighted $L_{2}$ -Spaces

Jae-Hwan Choi, Ildoo Kim

This study examines Cauchy problems governed by highly singular, time-measurable pseudo-differential operators (singular measurable families of Fourier multipliers). We show that t…

The stochastic Keller--Segel system in critical spaces

Jae-Hwan Choi, Ankit Kumar, Andrea Pitrone +2

We study stochastic, parabolic-parabolic Keller--Segel equations on the $d$ -dimensional torus in scaling critical Besov spaces, for $d \geq 3$ . Using stochastic maximal regularity…
