Convolution Algebraic Structures Defined by Hardy-Type Operators

open access: yesJournal of Function Spaces and Applications, 2013
The main aim of this paper is to show that certain Banach spaces, defined via integral kernel operators, are Banach modules (with respect to some known Banach algebras and convolution products on ℝ+).

The range of convolution operators [PDF]

open access: yesPacific Journal of Mathematics, 1984
Es sei G eine lokalkompakte, nicht-kompakte Gruppe und f eine p-fach \((p>1)\) integrierbare Funktion auf G. Der Autor zeigt, daß der Unterraum \(L^ 1(G)*f\) von \(L^ p(G)\) nicht abgeschlossen ist, falls f von Null verschieden ist. Mit Hilfe des Faktorisierungssatzes kann man daraus herleiten, daß auch M(G)*f nicht abgeschlossen ist, wobei M(G) die ...

Deep Learning–Assisted Differentiation of Four Peripheral Neuropathies Using Corneal Confocal Microscopy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peripheral neuropathies contribute to patient disability but may be diagnosed late or missed altogether due to late referral, limitation of current diagnostic methods and lack of specialized testing facilities. To address this clinical gap, we developed NeuropathAI, an interpretable deep learning–based multiclass classification ...

On the R-boundedness of stochastic convolution operators [PDF]

open access: yes, 2014
The $R$-boundedness of certain families of vector-valued stochastic convolution operators with scalar-valued square integrable kernels is the key ingredient in the recent proof of stochastic maximal $L^p$-regularity ...

Prediction of Myasthenia Gravis Worsening: A Machine Learning Algorithm Using Wearables and Patient‐Reported Measures

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Myasthenia gravis (MG) is a rare disorder characterized by fluctuating muscle weakness with potential life‐threatening crises. Timely interventions may be delayed by limited access to care and fragmented documentation. Our objective was to develop predictive algorithms for MG deterioration using multimodal telemedicine data ...

Geometric analysis of integral operators related to Touchard polynomials and generalized Bessel functions

open access: yesAIMS Mathematics
This article investigated the inclusion properties of Touchard polynomials $ Y_m(p, z) $ and generalized Bessel functions of the first kind $ \mathcal{G}_a(z) $, along with their associated convolution and integral operators, within the analytic function

On some operator equations in the space of analytic functions and related questions; pp. 81–87 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2013
We investigate extended eigenvalues, extended eigenvectors, and cyclicity problems for some convolution operators. By using the Duhamel product technique, we also estimate the norm of the inner derivation operator ΔA.

Littlewood-Paley-Stein type square functions based on Laguerre semigroups [PDF]

open access: yes, 2010
We investigate g-functions based on semigroups related to multi-dimensional Laguerre function expansions of convolution type. We prove that these operators can be viewed as Calderon-Zygmund operators in the sense of the underlying space of homogeneous ...

Sharp estimates for potential operators associated with Laguerre and Dunkl-Laguerre expansions

open access: yes, 2014
We study potential operators associated with Laguerre function expansions of convolution and Hermite types, and with Dunkl-Laguerre expansions. We prove qualitatively sharp estimates of the corresponding potential kernels.
