Hölder continuity of the minimizer of an obstacle problem with generalized Orlicz growth

Arttu Karppinen, Mikyoung Lee

We prove local C0,α- and C1,α-regularity for the local solution to an obstacle problem with non-standard growth. These results cover as special cases standard, variable e…

The weak Harnack inequality for unbounded supersolutions of equations with generalized Orlicz growth

Allami Benyaiche, Petteri Harjulehto, Peter Hästö +1

We study unbounded weak supersolutions of elliptic partial differential equations with generalized Orlicz (Musielak--Orlicz) growth. We show that they satisfy the weak Harnack ineq…

Removable sets in elliptic equations with Musielak-Orlicz growth

Iwona Chlebicka, Arttu Karppinen

We characterize, in the terms of intrinsic Hausdorff measures, the size of~removable sets for Hölder continuous solutions to elliptic equations with Musielak-Orlicz growth. In the…
