Various characterizations are given of the exponential Orlicz space L exp t r and the Orlicz -Lorentz space L exp t r , t r . By way of application we give a simple proof of the celebrated theorem of Brézis and Wainger concerning a limiting case of a Sobolev imbedding theorem.

✦ Synopsis
On the unit ball of an Orlicz function space the denting points, weak U denting points, and quasi-denting points coincide. But on the unit ball of an Orlicz sequence space the quasi-denting points are different from the denting points and weak U denting points. We also show that the weak U drop property and the Kadec᎐Klee property are equivalent in Orlicz spaces. Hence the weak drop property and the weak U drop property are independent properties in Banach spaces.

## Abstract Let Λ~__w,ϕ__~ be the Orlicz–Lorentz space. We study Gateaux differentiability of the functional ψ~__w,ϕ__~ (__f__) = $ \int \_{0} ^{\infty} $ __ϕ__ (__f__ \*)__w__ and of the Luxemburg norm. More precisely, we obtain the one‐sided Gateaux derivatives in both cases and we characterize
Criteria for strict monotonicity, lower local uniform monotonicity, upper local uniform monotonicity and uniform monotonicity of a Musielak Orlicz space endowed with the Amemiya norm and its subspace of order continuous elements are given in the cases of nonatomic and the counting measure space. To
For any separable Orlicz space L we describe all Orlicz subspaces in which N every function can be represented in the norm of L by the Vilenkin᎐Fourier N series. For Walsh᎐Fourier partial sums S w f a more precise result is obtained. n
