Multivariate vector sampling expansions in shift invariant subspaces [PDF]
arXiv, 2010 In this paper, we study multivariate vector sampling expansions on general finitely generated shift-invariant subspaces. Necessary and sufficient conditions for a multivariate vector sampling theorem to hold are given.

A few remarks on sampling of signals with small spectrum [PDF]
arXiv, 2011 Given a set $S$ of small measure, we discuss existence of sampling sequences for the Paley-Wiener space $PW_S$, which have both densities and sampling bounds close to the optimal ones.

Asymptotics of orthogonal polynomials via the Koosis theorem
, 2005 The main aim of this short paper is to advertize the Koosis theorem in the mathematical community, especially among those who study orthogonal polynomials. We (try to) do this by proving a new theorem about asymptotics of orthogonal polynomials for which

Invariance of Fréchet Frames under Perturbation [PDF]
arXiv, 2012 Motivating the perturbations of frames in Hilbert and Banach spaces, in this paper we introduce the invariance of Fr\'echet frames under perturbation. Also we show that for any Fr\'echet spaces, there is a Fr\'echet frame and any element has a series expansion.

arXiv, 2012 The concept of (p,q)-pair frames is generalized to (l,l^*)-pair frames. Adjoint (conjugate) of a pair frames for dual space of a Banach space is introduced and some conditions for the existence of adjoint (conjugate) of pair frames are presented.

No.1, 2012, pp. 116-120, 2013 In this short note we introduce and study a particular type of Schauder frames, namely, \Phi-Schauder frames.

Weyl-Heisenberg frames for subspaces of L^2(R)
, 1998 We give sufficient conditions for translates and modulates of a function g in L^2(R) to be a frame for its closed linear span. Even in the case where this family spans all of L^2(R), wou conditions are significantly weaker than the previous known ...
