Generalized homogeneity of finite and of countable topological spaces

open access: yesRocky Mountain Journal of Mathematics, 1988
A topological space X is said to be homogeneous with respect to a class M of functions of X onto itself provided that for every two points \(p,q\in X\), there is an element \(f\in M\) with \(f(p)=q\). The authors consider three classes of functions, namely: homeomorphisms, open continuous surjections, and continuous surjections.

Potential operators, maximal functions, and generalizations of A∞ [PDF]

open access: yes, 2003
We derive weighted norm estimates which relate integral operators of potential type (fractional integrals) to corresponding maximal operators (fractional maximal operators). We also derive norm estimates for the maximal operators.

Prediction of Surface Topography Parameters in Direct Laser Interference Patterning of Stainless Steel Using Infrared Monitoring and Convolutional Neural Networks

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents an infrared monitoring approach for direct laser interference patterning (DLIP) combined with a convolutional neural network (CNN). Thermal emission data captured during structuring are used to predict surface topography parameters.

Generalized Campanato space over non‐homogeneous space and its applications

open access: yesMathematische Nachrichten
Abstract The authors introduce generalized Campanato space with regularized condition over non‐homogeneous space, and study its basic properties including the John–Nirenberg inequality and equivalent characterizations. As applications, the boundedness of fractional type Marcinkiewicz integral and its commutator on generalized Morrey ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

The Sharp Maximal Function on Spaces of Generalized Homogeneous Type

open access: yesJournal of Functional Analysis, 1997
The paper deals with harmonic analysis on spaces of generalized type. The spaces considered were defined by \textit{A. Carbery}, \textit{J. Vance}, \textit{S. Wainger} and \textit{J. Wright} [ibid. 132, 119-140 (1995)] stimulated by the studies of the Hilbert transform and maximal functions associated to the curves on certain nilpotent Lie groups.

Bernstein and Markov-type inequalities for polynomials on Lp(μ) spaces

open access: yes, 2019
In this work we discuss generalizations of the classical Bernstein and Markov type inequalities for polynomials and we present some new inequalities for the kth Frechet derivative of homogeneous polynomials on real and complex L-p (mu) spaces.

Energies, group-invariant kernels and numerical integration on compact manifolds

open access: yes, 2009
The purpose of this paper is to derive quadrature estimates on compact, homogeneous manifolds embedded in Euclidean spaces, via energy functionals associated with a class of group-invariant kernels which are generalizations of zonal kernels on the ...
