A regularity theory for second-order parabolic partial differential equations in weighted mixed norm Sobolev-Zygmund spaces
Jae-Hwan Choi, Junhee Ryu
We develop an optimal regularity theory for parabolic partial differential equations in weighted mixed norm Sobolev-Zygmund spaces. The results extend the classical Schauder estima…

A regularity theory for evolution equations with time-measurable pseudo-differential operators in weighted mixed-norm Sobolev-Lipschitz spaces
Jae-Hwan Choi
This paper investigates the existence, uniqueness, and regularity of solutions to evolution equations with time-measurable pseudo-differential operators in weighted mixed-norm Sobo…
