Abstract:  We give some equivalent conditions (independent from the Young functions) for inclusions between some classes of $X^\Phi$ spaces, where $\Phi$ is a Young function and $X$ is a quasi-Banach function space on a $\sigma$-finite measure space $(\Omega,\mathcal{A},\mu)$.
Keywords:  Young function; Orlicz space; quasi-Banach function space; inclusion
Classification MSC:  46E30
