Haar measure for non-Hausdorff locally compact groups

open access: yes, 2023
The paper describes two possible ways of extending the definition of Haar measure to non-Hausdorff locally compact groups. The first one forces compact sets to be measurable: with this construction, a counterexample to the existence of the Haar measure ...

HAUSDORFF AND HARMONIC MEASURES ON NON-HOMOGENEOUS CANTOR SETS

open access: yes, 2015
. We consider (not self-similar) Cantor sets defined by a sequence of piecewise linear functions. We prove that the dimension of the harmonic measure on such a set is strictly smaller than its Hausdorff dimension.

Solvability of infinite system of integral equations of Hammerstein type in three variables in tempering sequence spaces c0β{c}_{0}^{\beta } and ℓ1β{\ell }_{1}^{\beta }

open access: yesDemonstratio Mathematica
The objective of this study is to determine the criteria under which the infinite system of integral equations in three variables has a solution in the Banach tempering sequence space c0β{c}_{0}^{\beta } and ℓ1β{\ell }_{1}^{\beta }, utilizing the Meir ...

Bayesian Optimization of Grayscale Patterns for Layer‐Height Accuracy in Projection Multi‐Photon 3D Printing

open access: yesLaser &Photonics Reviews, EarlyView.
Bayesian optimization combined with in situ quantitative phase imaging enables autonomous correction of layer‐height deviations in projection multi‐photon lithography. By jointly tuning model parameters and grayscale exposure settings, the method achieves more uniform and accurate layers within 300 prints, offering a fast, data‐efficient route to ...

Corrigendum to ” Matrix transformation and application of Hausdorff measure of non-compactness on newly defined Fibo-Pascal sequence spaces” [ Filomat 38:4 (2024), 1185-1196]

open access: yesFilomat
This corrigendum is to express the definition of the Fibo-Pascal matrix PF = (pFnk) involving Fibonomial coefficient and its inverse [PF]-1 = ((pF)-1nk) were given in[2]. So, the last two paragraphs of the introductory section in [1] should be replaced by the following statements.

A Note on Sobolev‐Lorentz Capacity and Hausdorff Measure

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT In this paper, we give an elementary proof that sets of zero p,1$p,1$‐Sobolev‐Lorentz capacity are Hn−p$\mathcal {H}^{n-p}$‐null sets, independently of nonlinear potential theory. We further show that there exists a set of Sobolev‐Lorentz‐(p,1)$(p,1)$ capacity equal to zero with Hausdorff dimension equal n−p$n-p$.

Norms and compactness of operators on absolute weighted mean summable series

open access: yesKuwait Journal of Science, 2016
In a recent paper [16], we characterized the classes of triangular matrix transformations mapping the spaces INpI and INqIk into the spaces INqIk and INqI, respectively, where the space INpIk, of series summable by absolute summability method.

Relationship Between Limiting K‐Spaces and J‐Spaces in the Real Interpolation

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT In the paper, “Description of the K$K$‐Spaces by Means of J$J$‐Spaces and the Reverse Problem,” Mathematische Nachrichten 296, no. 9 (2023), 4002–4031, we have established conditions under which the limiting K$K$‐space (X0,X1)0,q,b;K$(X_0,X_1)_{0,q,b;K}$, involving a slowly varying function b$b$, can be described by means of the J$J$‐space (X0,

Generalised Hausdorff measure of sets of Dirichlet non-improvable matrices in higher dimensions

open access: yes, 2023
Let $\psi:\mathbb R_{+}\to \mathbb R_{+}$ be a nonincreasing function. A pair $(A,\mathbf b),$ where $A$ is a real $m\times n$ matrix and $\mathbf b\in\mathbb R^{m},$ is said to be $\psi$-Dirichlet improvable, if the system $$\|A\mathbf q +\mathbf b ...

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.
