Equivalent quasi-norms on generalized Orlicz spaces

In this paper we show that the equivalence among the classical quasi-norms of the generalized Orlicz spaces XΦ — the Orlicz quasi-norm, the Luxemburg quasi-norm and the Amemiya quasi-norm — holds under some mild conditions on the underlying quasi-Banach function space X — mainly the weak Fatou prope...

Sumario:In this paper we show that the equivalence among the classical quasi-norms of the generalized Orlicz spaces XΦ — the Orlicz quasi-norm, the Luxemburg quasi-norm and the Amemiya quasi-norm — holds under some mild conditions on the underlying quasi-Banach function space X — mainly the weak Fatou property — improving previous results of [R. DEL CAMPO, A. FERNANDEZ ´ , F. MAYORAL, F. NARANJO AND E. A. SANCHEZ ´ -PEREZ ´ , When and where the Orlicz and Luxemburg (quasi-) norms are equivalent?, J. Math. Anal. Appl. 249, 1 (2020)] for which some lattice convexity requirements for the quasi-Banach function space X were needed.
