Our concern in this paper lies with trace spaces for weighted Sobolev spaces, when the weight is a power of the distance to a point at the boundary. For a large range of powers we give a full description of the trace space.

We study noneffective weights in the framework of variable exponent Lebesgue spaces, and we show that Lp(⋅)(Ω)=Lωp(⋅)(Ω) if and only if ω(x)1/p(x)~constant in the set where p(⋅)

First the characteristic of monotonicity of any Banach lattice X is expressed in terms of the left limit of the modulus of monotonicity of X at the point 1. It is also shown that for Köthe spaces the classical characteristic of monotonicity is the s

We are interested in the widest possible class of Orlicz functions $\Phi$ such that the easily calculable quasinorm $[f]_{\Phi,p}:=\Vert f\Vert_{E}\{I_{\Phi}(\frac{f}{\Vertf\Vert_{E}})\}^{1\slash p}$ if $f\neq0$ and $[f]_{\Phi,p}=0$ if $f=0$ , on the

We consider the linearized and nonlinear problems arising from the motion of fluid flow around a rotating rigid body. We are interested in very weak solutions of these problems.

Geometric properties being the rearrangement counterparts of strict monotonicity, lower local uniform monotonicity and upper local uniform monotonicity in some symmetric spaces are considered. The relationships between strict monotonicity, upper loca

We study the boundary-value problem ũt = Δxũ(x,t), ũ(x, 0) = u(x), where x ∈ Ω, t ∈ (0,T), Ω ⊆ ℝn−1 is a bounded Lipschitz boundary domain, u belongs to a certain Orlicz–Slobodetskii space YR,R(Ω). Under certain assumptions on the

We prove an estimate for the trace operator in spaces whose weak derivatives are in Orlicz spaces without constraints upon the growth of the generating Young function. This extends the known trace theorems established in Orlicz-Sobolev spaces, where
