Pointwise convergence of sequential Schrödinger means [PDF]
Journal of Inequalities and Applications, 2023 We study pointwise convergence of the fractional Schrödinger means along sequences t n $t_{n}$ that converge to zero. Our main result is that bounds on the maximal function sup n | e i t n ( − Δ ) α / 2 f | $\sup_{n} |e^{it_{n}(-\Delta )^{\alpha /2}} f| $

Open Mathematics, 2015 The paper presents a new type of density topology on the real line generated by the pointwise convergence, similarly to the classical density topology which is generated by the convergence in measure.

On ρ−statistical convergence of order α of sequences of function [PDF]
E-Journal of Analysis and Applied Mathematics, 2022 In this study, by using definition of ρ-statistical convergence which was defined by Çakallı, we introduce the concepts of pointwise wαρ (f )-summability, pointwise ρ-statistical convergence of order α and uniform ρ-statistical convergence of order α ...

Approximation properties of multivariate exponential sampling series
Karpatsʹkì Matematičnì Publìkacìï, 2021 In this paper, we generalize the family of exponential sampling series for functions of $n$ variables and study their pointwise and uniform convergence as well as the rate of convergence for the functions belonging to space of $\log$-uniformly continuous

Nonparametric Pointwise Estimation for a Regression Model with Multiplicative Noise
Journal of Function Spaces, 2021 In this paper, we consider a general nonparametric regression estimation model with the feature of having multiplicative noise. We propose a linear estimator and nonlinear estimator by wavelet method.

Pointwise Wavelet Estimations for a Regression Model in Local Hölder Space
Axioms, 2022 This paper considers an unknown functional estimation problem in a regression model with multiplicative and additive noise. A linear wavelet estimator is first constructed by a wavelet projection operator.

A NEW APPROACH TO EGOROV’S THEOREM BY MEANS OF 𝛼𝛽-STATISTICAL IDEAL CONVERGENCE
Проблемы анализа, 2022 In this work, we introduce the 𝛼𝛽-statistical pointwise ideal convergence, 𝛼𝛽-statistical uniform ideal convergence, and 𝛼𝛽-equi-statistical ideal convergence for sequences of fuzzy-valued functions.

A note on Hausdorff convergence of pseudospectra [PDF]
Opuscula Mathematica, 2022 For a bounded linear operator on a Banach space, we study approximation of the spectrum and pseudospectra in the Hausdorff distance. We give sufficient and necessary conditions in terms of pointwise convergence of appropriate spectral quantities.

Well-posedness of the solution of the fractional semilinear pseudo-parabolic equation
Boundary Value Problems, 2020 This article concerns the Cauchy problem for the fractional semilinear pseudo-parabolic equation. Through the Green’s function method, we prove the pointwise convergence rate of the solution.
