Several works have revealed the inclusion properties between the Orlicz spaces, which are complicated in the proof process and very difficult to apply.
Kim Jin Ju, a lecturer at the Faculty of Applied Mathmatics, has formulated a necessary and sufficient condition for the existence of inclusion properties between weighted and weighted weak Orlicz spaces, which is a more generalized space than an Orlicz space, using the characteristic function of a sphere.
