Generalized Appell polynomials and Fueter-Bargmann transforms in the polyanalytic setting [PDF]
Analysis and Applications, 2021 ispaper dealswith some special integral transforms in the seing of quaternionic valued slice polyanalytic functions. In particular, using the polyanalytic Fueter mappings it is possible to construct a new family of polynomials which are called the ...

Some new results on the weaving of K-g-frames in Hilbert spaces
Open Mathematics, 2021 In this paper, we provide some conditions for a K-woven pair of K-g-frames to be preserved under an operator and particularly, we report that applying two different operators to a K-woven pair of K-g-frames can leave them K-woven.

Controlled K-Fusion Frame for Hilbert Spaces
Moroccan Journal of Pure and Applied Analysis, 2021 K-fusion frames are a generalization of fusion frames in frame theory. In this paper, we extend the concept of controlled fusion frames to controlled K-fusion frames, and we develop some results on the controlled K-fusion frames for Hilbert spaces, which

Relay fusion frames in Banach spaces
Open Mathematics, 2023 The relay fusion frames have been recently introduced in Hilbert spaces to model sensor relay networks and distributed sensor relay systems, which are deeply connected with compressed sensing.

Instantaneous Frequency-Embedded Synchrosqueezing Transform for Signal Separation
Frontiers in Applied Mathematics and Statistics, 2022 The synchrosqueezing transform (SST) and its variants have been developed recently as an alternative to the empirical mode decomposition scheme to model a non-stationary signal as a superposition of amplitude- and frequency-modulated Fourier-like ...

On the limiting behaviour of needlets polyspectra [PDF]
, 2013 This paper provides quantitative Central Limit Theorems for nonlinear transforms of spher-ical random fields, in the high frequency limit. The sequences of fields that we consider arerepresented as smoothed averages of spherical Gaussian eigenfunctions and

Controlled Continuous g-Frames in Hilbert C*-Modules
Moroccan Journal of Pure and Applied Analysis, 2020 Frame Theory has a great revolution in recent years. This Theory have been extended from Hilbert spaces to Hilbert C*-modules. The purpose of this paper is the introduction and the study of the concept of Controlled Continuous g-Frames in Hilbert C ...

OPTIMAL LINE PACKINGS FROM FINITE GROUP ACTIONS
Forum of Mathematics, Sigma, 2020 We provide a general program for finding nice arrangements of points in real or complex projective space from transitive actions of finite groups. In many cases, these arrangements are optimal in the sense of maximizing the minimum distance.

Almost Diagonalization of $\Psi$DO’s Over Various Generalized Function Spaces [PDF]
Sarajevo Journal of MathematicsInductive and projective type sequence spaces of sub- and super-exponential growth, and the corresponding inductive and projective limits of modulation spaces are considered as a framework for almost diagonalization of pseudo-differential operators ...

A density condition for interpolation on the Heisenberg group [PDF]
, 2010 (N). We prove a necessary and sufficient density conditionin order that such subsspaces possess the interpolation property with respect toa class of discrete subsets of N that includes the integer lattice.
