INVERTIBILITY OF THE GABOR FRAME OPERATOR ON THE WIENER AMALGAM SPACE
Wiener amalgam space Gabor frame Walnut representation Wiener’s Lemma
2015/12/10
We use a generalization of Wiener’s 1/f theorem to prove that for a Gabor frame with the generator in the Wiener amalgam space W (L∞, `1 )(Rd), the corresponding frame operator is invertible on this s...
Restricted Invertibility and the Banach-Mazur distance to the cube
Restricted Invertibility the Banach-Mazur distance cube Functional Analysis
2012/6/19
We prove a normalized version of the restricted invertibility principle obtained by Spielman-Srivastava. Applying this result, we get a new proof of the proportional Dvoretzky-Rogers factorization the...
One side invertibility for implicit hyperbolic systems with delays
Left invertibility implicit systems system with delays
2010/11/29
This paper deals with left invertibility problem of implicit hyperbolic systems with delays in infinite dimensional Hilbert spaces. From a decomposition procedure, invertibility for this class of syst...
Differential and invertibility properties of BLAKE（full version）
BLAKE cryptanalysis hash functions
2010/2/1
BLAKE is a hash function selected by NIST as one of the 14 second round candidates for
the SHA-3 Competition. In this paper, we follow a bottom-up approach to exhibit properties of BLAKE and of its b...
