This paper introduces some notions of e ective dimension for weighted
function spaces. A space has low e ective dimension if the smallest ball
in it that contains a function of variance 1, has no fu...

We study the homogeneous equation (*) $ u' = \Delta u$, $t > 0$, $u(0)=f\in wX$, where $wX$ is a weighted Banach space, $w(x)= (1+||x||)^k$, $x\in \r^n$ with $k\ge 0$, $ \Delta$ is the Laplacian, $Y$ ...

We provide some new estimates for distances in harmonic function spaces of several variables related to mixed norm spaces.Some of them extend previously known assertions in this direction in the unit ...

Anisotropic weighted Sobolev spaces Bessel potential spaces Besov spaces Holder spaces noncomplete Riemannian manifolds with boundary
2012/4/18
A rather complete investigation of anisotropic Bessel potential, Besov, and H\"older spaces on cylinders over (possibly) noncompact Riemannian manifolds with boundary is carried out. The geometry of t...

Moyal multiplier algebras test function spaces of type S
2011/1/17
The Gel’fand-Shilov spaces of type S are considered as topological algebras with respect
to the Moyal star product and their corresponding algebras of multipliers are defined and
investigated.

For a non-isolated point x of a topological space X let nw (x) be the smallest cardinality of a family N of infinite subsets of X such that each neighborhood O(x) X of x contains a set N 2 N.
The homotopy theory of function spaces: A survey
Function space monoid of self-equivalence free loop space
2010/11/30
We survey research on the homotopy theory of the space map(X, Y )consisting of all continuous functions between two topological spaces. We summarize progress on various classification problems for the...
SUPERPOSITION OPERATORS BETWEEN VARIOUS ALMOST PERIODIC FUNCTION SPACES AND APPLICATIONS
almost periodic function superposition operator evolution equation differential equation asymptotically almost periodic function almost automorphic function
2008/11/28
We study the superposition operators (also called Nemytskii operators) between spaces
of almost periodic functions with values in a complete metric space or in a Banach
space. We establish new resul...
