Moyal multiplier algebras of the test function spaces of type S
Moyal multiplier algebras test function spaces of type S
font style='font-size:12px;'>
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.
Weak type estimates of Marcinkiewicz integrals on the weighted Hardy spaces and weighted Herz-type Hardy spaces
Marcinkiewicz integrals weighted Hardy spaces weighted
font style='font-size:12px;'>
2011/1/17
TheMarcinkiewicz integral is essentially a Littlewood-Paley g-function,which plays a important role in harmonic analysis. In this article, by using the atomic decomposition theory of weighted Hardy sp...

The main results of this note are:• It is consistent that every subparacompact space X of size !1 is a D-space.
On local comparison between various metrics on Teichmüller spaces
Teichm¨uller space Teichm¨uller metric quasiconformal metric
font style='font-size:12px;'>
2011/1/20
There are several Teichm¨uller spaces associated to a surface of infinite topological type, after the choice of a particular basepoint ( a complex or a hyperbolic structure on the surface). These spac...
Various characterizations of Besov-Dunkl spaces
Dunkl operators Dunkl transform Dunkl translation operators
font style='font-size:12px;'>
2011/2/28
In this paper, different characterizations of the Besov-Dunkl spaces, previously considered in [1, 2, 3, 11], are given. We provide equivalence between these characterizations, using the Dunkl transla...
On causal properties of symmetric Lorentzian spaces
causal properties symmetric Lorentzian spaces
font style='font-size:12px;'>
2011/1/18
The causal properties of Lorentzian symmetric spaces are investigated in the paper. There is proved the global hyperbolicity of the Cahen–Wallach Lorentzian symmetric spaces, corresponding to solvable...
Representation spaces of pretzel knots
Representation spaces pretzel knots
font style='font-size:12px;'>
2011/1/21
We study the representation spaces R(K; i) as appearing in Kronheimer and Mrowka's framed instanton knot Floer homology, for a class of pretzel knots. In particular, for pretzel knots P(p; q; r) with ...
Banach Gabor frames with Hermite functions: polyanalytic spaces from the Heisenberg group
Gabor frames Heisenberg group Hermite functions
font style='font-size:12px;'>
2011/2/23
Gabor frames with Hermite functions are equivalent to sampling sequences in true Fock spaces of polyanalytic functions. In the L2-case, such an equivalence follows from the unitarity of the polyanalyt...
Multiple G-Itô integral in the G-expectation space
Sublinear expectation G-Brownian motion G-Itˆ o integral
font style='font-size:12px;'>
2011/1/17
In this paper, motivated by mathematic finance we introduce the multiple G-Itˆo integral in the G-expectation space, then investigate how to calculate. We get the the relationship between Hermite...
A $c_0$ saturated Banach space with tight structure
c0 saturated Banach spaces space of operators saturated norms hereditarily
font style='font-size:12px;'>
2011/1/21
It is shown that variants of the HI methods could yield objects closely connected to the classical Banach spaces. Thus we present a new c0 saturated space, denoted as X0,with rather tight structure.
Radon-Nikodým compact spaces of low weight and Banach spaces
Radon-Nikod´ ym compact quasi Radon-Nikod´ ym compact
font style='font-size:12px;'>
2011/2/28
We prove that a continuous image of a Radon-Nikod´ym compact of weight less than b is Radon-Nikod´ym compact. As a Banach space counter-part, subspaces of Asplund generated Banach spaces o...
Periodic windows distribution resulting from homoclinic bifurcations in the two-parameter space
Homoclinic systems Periodic windows Bifurcation
font style='font-size:12px;'>
2010/12/28
Periodic solution parameters, in chaotic dynamical systems, form periodic windows with characteristic distribution in two-parameter spaces. Recently, general properties of this organization have been ...
Continuous C*-algebras over topological spaces
Continuous C*-algebras topological spaces
font style='font-size:12px;'>
2011/1/18
We define continuous C*-algebras over a topological space X and establish some basic results. If X is a locally compact Hausdorff space, continuous C*-algebras over X are equivalent to ordinary contin...
Fluid-induced pattern-formation in 3D photonic crystals with spatially varying surface functionalization
3D photonic spatially varying surface functionalization
font style='font-size:12px;'>
2010/12/28
We introduce a 3D porous photonic crystal whose inner surfaces are chemically functionalized in arbitrary spatial patterns with micro-scale resolution. We use this platform to demonstrate pattern-form...

A metric space is a set M together with a real-valued function d(x, y)defined for x, y ∈ M that satisfies the following three conditions. First,d(x, y) ≥ 0 for every x, y ∈ M, and d(x, y) = 0 if and o...
