A Sobolev-Type Upper Bound for Rates of Approximation by Linear Combinations of Heaviside Plane Waves
For sufficiently differntiable functions, there are derived estimates of rates of approximation by linear combinations of Heaviside plane waves converging to zero exponentially fast. The estimates depend on Sobolev seminorms and the number o...

Best Approximation by Linear Combinations of Characteristic Functions of Half-Spaces.
It is shown that for any positive integer n and any Lp-function f there exist n half-spaces such that f has a best approximation by a linear combination of their characteristic functions. Further, any sequ...

Integral Combinations of Heavisides
A sufficiently smooth function of d variables that decays fast enough at infinity can be represented pointwise by an integral combination of Heaviside plane waves (i.e., characteristic functions of closed half<...

Construction of Function Spaces Close to L∞ with Associate Space Close to L1
The paper introduces a variable exponent space X which has in common with L^∞ [0, 1]) the property that the space C([0, 1]) of continuous functions on [0, 1] is a closed linear subspace in it. The associate spa...

From strong to very weak solutions to the Stokes system with Navier boundary concitions in the half-space
We consider the Stokes problem with slip-type boundary conditions in the half-space R-+(n), with n >= 2. The weighted Sobolev spaces yield the functional framework. We first study generalized and strong solutions a...

On asymptotic expansion of the harmonic Berezin transform on the half-space
We give a complete asymptotic expansion of the Berezin transform associated to the Bergman space of harmonic functions on the half-space H := {(x, y) is an element of Rn+1; x is an element of R-n, y > 0} that are s...
