On Musielak N-functions

Abstract

In this paper, the concept of Musielak N-functions and Musielak-Orlicz spaces generated by them well be introduced. Facts and results of the measure theory will be applied to consider properties, calculus and basic approximation of Musielak N-functions and their Musielak-Orlicz spaces. Finally, the relationship between Musielak N-functions and Musielak-Orlicz functions and thier Musielak-Orlicz spaces will be considered using facts and results of the measure theory too
