Besov-type spaces for the κ-Hankel wavelet transform on the real line
Concrete Operators, 2021 In this paper, we shall introduce functions spaces as subspaces of Lpκ (ℝ) that we call Besov-κ-Hankel spaces and extend the concept of κ-Hankel wavelet transform in Lpκ(ℝ) space.

Quadratic phase S-Transform: Properties and uncertainty principles
e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023 In this paper, a novel quadratic phase S-transform (QPST) is proposed, by generalizing the S-transform (ST) with five parameters a, b, c,d and e. QPST displays the time and quadratic phase domain-frequency information jointly in the time-frequency plane.

Some results on vanishing moments of wavelet packets, convolution and cross-correlation of wavelets
Arab Journal of Mathematical Sciences, 2019 A formula for calculating moments for wavelet packets is derived and a sufficient condition for moments of wavelet packets to be vanishing is obtained.

Spectral Algorithms for MRA Orthonormal Wavelets [PDF]
, 2018 Producción CientíficaOperator techniques lead to spectral algorithms to compute scaling functions and wavelets associated with multiresolution analyses (MRAs). The spectral algorithms depend on the choice of pairs of suitable orthonormal bases (ONBs).

Totally positive refinable functions with general dilation M [PDF]
, 2017 We construct a new class of approximating functions that are M-refinable and provide shape preserving approximations. The refinable functions in the class are smooth, compactly supported, centrally symmetric and totally positive.

Métodos tiempo-frecuencia basados en la transformada wavelet
Revista de Matemática: Teoría y Aplicaciones, 2012 La información contenida en una señal analógica se evidencia por su representación numérica. El par de Fourier en dos representaciones complementarias explicita las estructuras temporales y frecuenciales. Para detectar y caracterizar eventos que combinan

A Lévy-Ciesielski expansion for quantum Brownian motion and the construction of quantum Brownian bridges [PDF]
, 2007 We introduce "probabilistic" and "stochastic Hilbertian structures". These seem to be a suitable context for developing a theory of "quantum Gaussian processes". The Schauder system is utilised to give a Lévy-Ciesielski representation of quantum (bosonic)

Reproducing Kernel Hilbert Space and Coalescence Hidden-variable Fractal Interpolation Functions
Demonstratio Mathematica, 2019 Reproducing Kernel Hilbert Spaces (RKHS) and their kernel are important tools which have been found to be incredibly useful in many areas like machine learning, complex analysis, probability theory, group representation theory and the theory of integral ...

CALDERÓN’S INVERSE PROBLEM WITH A FINITE NUMBER OF MEASUREMENTS
Forum of Mathematics, Sigma, 2019 We prove that an $L^{\infty }$ potential in the Schrödinger equation in three and higher dimensions can be uniquely determined from a finite number of boundary measurements, provided it belongs to a known finite dimensional subspace ${\mathcal{W}}$. As a
