The Atkinson Theorem in Hilbert C*-Modules over C*-Algebras of Compact Operators [PDF]
The concept of unbounded Fredholm operators on Hilbert C*-modules over an arbitrary C*-algebra is discussed and the Atkinson theorem is generalized for bounded and unbounded Feredholm operators on Hilbert C*-modules over C*-algebras of compact operators.

A sufficient condition for the boundedness of operator-weighted martingale transforms and Hilbert transform [PDF]
Let W be an operator weight taking values almost everywhere in the bounded positive invertible linear operators on a separable Hilbert space H. We show that if W and its inverse W−1 both satisfy a matrix reverse Holder property introduced in [2], then ...

The Hilbert transform is essentially the only singular operator in one dimension. This undoubtedly make it one of the most important linear operator in harmonic analysis.

Building on past work showing that the Hilbert transform can be used for edge feature enhancement, a new edge feature enhancement method is developed using a two‐dimensional (2D) isotropic Hilbert transform of the Cauchy distribution.

A characterization of the Hilbert transform [PDF]
Let \(H\) be the Hilbert transform on the real line, \[ Hf(x)= {1\over\pi} \text{p.v. }\int^\infty_{-\infty} f(x- y) {dy\over y}\quad\text{for }x\in\mathbb{R}. \] Let \(T\) be a bounded linear operator on \(L^2(\mathbb{R})\) satisfying: (i) \(T\) maps real valued functions into real valued functions, (ii) \(T\) commutes with translations, (iii) \(-T^2=

Hölder norm estimate for a Hilbert transform in Hermitian Clifford analysis [PDF]
A Hilbert transform for Holder continuous circulant (2 x 2) matrix functions, on the d-summable (or fractal) boundary I" of a Jordan domain Omega in a"e(2n) , has recently been introduced within the framework of Hermitean Clifford analysis. The main goal

Time-Frequency Analysis of Noisy Vibration Signal Based on Improved Hilbert-Huang Transform
Aimed at the phenomenon of modal confusion and lack of practical significance of instantaneous frequency caused by Hilbert-Huang transform (HHT) noisy vibration signal time-frequency analysis, complete ensemble empirical mode decomposition with adaptive ...
