Poincaré-type inequalities in Musielak spaces
Ahmed Youssfi, Youssef Ahmida
In this paper we investigate Poincaré-type integral inequalities in the functional Musielak structure. We extend the ones already well known in Sobolev, Orlicz and variable exponen…

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…

Some approximation results in Musielak-Orlicz spaces
Ahmed Youssfi, Youssef Ahmida
We give sufficient conditions for the continuity in norm of the translation operator in the Musielak-Orlicz LM spaces. An application to the convergence in norm of approximate iden…
