Density of the Set of Generators of Wavelet Systems
Carlos Cabrelli, Ursula Molter
Given a function in $ \LL^2(\R^d)$, the affine (wavelet) system generated by , associated to an invertible matrix and a lattice $\zG$, is the collection of functions $\{…
Newton-Hensel Interpolation Lifting
Martin Avendaño, Teresa Krick, Ariel Pacetti
The main result of this paper is a new version of Newton-Hensel lifting that relates to interpolation questions. It allows one to lift polynomials in from information modulo…
Damping of vortex waves in a superfluid
H. M. Cataldo
The damping of vortex cyclotron modes is investigated within a generalized quantum theory of vortex waves. Similarly to the case of Kelvin modes, the friction coefficient turns out…
Local bases for refinable spaces
Carlos Cabrelli, Sigrid Heineken, Ursula Molter
We provide a new representation of a refinable shift invariant space with a compactly supported generator, in terms of functions with a special property of homogeneity. In particul…
Phase resonances in obliquely illuminated compound gratings
Ricardo A. Depine, Angela N. Fantino, Susana I. Grosz +1
The existence of phase resonances in obliquely illuminated, perfectly conducting compound gratings is investigated. The diffraction problem of a p-polarized plane wave impinging on…
Thin-shell wormholes in dilaton gravity
Ernesto F. Eiroa, Claudio Simeone
In this work we construct charged thin-shell Lorentzian wormholes in dilaton gravity. The exotic matter required for the construction is localized in the shell and the energy condi…
