Calderón-Zygmund estimates for double phase problems with matrix weights

Sun-Sig Byun, Yumi Cho, Seungjin Ryu

We establish an optimal Calderón-Zygmund theory for nonuniformly elliptic double phase problems with matrix weights. For $1 < p < q < \infty$ , $a (\cdot) \in C^{0, α} (Ω)$ ( $0 < α \leq 1$ ), and a…

Parabolic equations with unbounded lower-order coefficients in Sobolev spaces with mixed norms

Doyoon Kim, Seungjin Ryu, Kwan Woo

We prove the Lp,q-solvability of parabolic equations in divergence form with full lower-order terms. The coefficients and non-homogeneous terms belong to mixed Lebesgue spaces with…
