Gossez's approximation theorems in the Musielak-Orlicz-Sobolev spaces
Youssef Ahmida, Iwona Chlebicka, Piotr Gwiazda +1
We prove the density of smooth functions in the modular topology in the Musielak-Orlicz-Sobolev spaces essentially extending the results of Gossez \cite{GJP2} obtained in the Orlic…

Well-posedness of parabolic equations in the non-reflexive and anisotropic Musielak-Orlicz spaces in the class of renormalized solutions
Iwona Chlebicka, Piotr Gwiazda, Anna Zatorska-Goldstein
We prove existence and uniqueness of renormalized solutions to general nonlinear parabolic equation in Musielak-Orlicz space avoiding growth restrictions. Namely, we consider \[\pa…
