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…
Complete intersections in toric ideals
Eduardo Cattani, Raymond Curran, Alicia Dickenstein
We present examples which show that in dimension higher than one or codimension higher than two, there exist toric ideals I_A such that no binomial ideal contained in I_A and of th…
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…
On the embedding problem for representations
Ariel Pacetti
Let denote the double cover of corresponding to the element in where transpositions lift to elements of order 2 and the product of two disjoint tra…
