Some approximation results in time and space dependent Musielak spaces
Youssef Ahmida, Ahmed Youssfi
We provide density results for smooth functions in non-reflexive Musielak spaces defined up on time- and space- dependent modular functions. These Musielak spaces encompass a broad…

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…

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…
