چکیده
The main contribution of this paper is twofold. First, some new sufficient conditions, under which the shift-invariant system is a frame for L(R), were established. Second, those sufficient conditions are used to obtain some new results about Gabor frames. 2000 Mathematics Subject Classification. 42C15, 42C40.

Shift Invariant Spaces and Shift Preserving Operators on Locally Compact Abelian Groups
We investigate shift invariant subspaces of $L^2(G)$, where $G$ is a locally compact abelian group. We show that every shift invariant space can be decomposed as an orthogonal sum of spaces each of which is generated by a single function whose shifts form a Parseval frame. For a second countable locally compact abelian group $G$ we prove a useful Hilbert space isomorphism, introduce range funct...
متن کاملMulti-Channel Sampling on Shift-Invariant Spaces with Frame Generators
Let φ be a continuous function in L(R) such that the sequence {φ(t− n)}n∈Z is a frame sequence in L(R) and assume that the shift-invariant space V (φ) generated by φ has a multi-banded spectrum σ(V ). The main aim in this paper is to derive a multi-channel sampling theory for the shift-invariant space V (φ). By using a type of Fourier duality between the spaces V (φ) and L[0, 2π] we find necess...

We discuss the asymptotic behaviour of solutions for the nonlocal quasilinear hyperbolic problem of Kirchhoff Type [ u_{tt}-phi (x)||nabla u(t)||^{2}Delta u+delta u_{t}=|u|^{a}u,, x in mathbb{R}^{N} ,,tgeq 0;,]with initial conditions $u(x,0) = u_0 (x)$ and $u_t(x,0) = u_1 (x)$, in the case where $N geq 3, ; delta geq 0$ and $(phi (x))^{-1} =g (x)$ is a positive function lying in $L^{N/2}(mathb...
متن کاملGeneralized Continuous Frames for Operators
In this note, the notion of generalized continuous K- frame in a Hilbert space is defined. Examples have been given to exhibit the existence of generalized continuous $K$-frames. A necessary and sufficient condition for the existence of a generalized continuous $K$-frame in terms of its frame operator is obtained and a characterization of a generalized continuous $K$-frame for $ mathcal{H} $ wi...
متن کاملShift Invariant Spaces for Local Fields
This paper is an investigation of shift invariant subspaces of L2(G), where G is a locally compact abelian group, or in general a local field, with a compact open subgroup. In this paper we state necessary and sufficient conditions for shifts of an element of L2(G) to be an orthonormal system or a Parseval frame. Also we show that each shift invariant subspace of L2(G) is a direct sum of princi...
