Binary Orlicz spaces
S. V. Astashkin Samara National Research University, Samara, Russia
Abstract:
A subspace $H$ of a rearrangement invariant space $X$ is strongly embedded in $X$ if, on $H$, convergence in the $X$-norm is equivalent to convergence in measure. Necessary and sufficient conditions on an Orlicz function $M$ are obtained under which the unit ball of any subspace strongly embedded in the Orlicz space $L_M$ has equi-absolutely continuous norms in $L_M$.
Keywords:
rearrangement invariant space, strongly embedded subspace, Orlicz function, Orlicz space, Matuszewska–Orlicz indices.
