Order Structure of the Figà‐Talamanca‐Herz Algebra
International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 We study the interplay between the order structure and the p‐operator space structure of Figà‐Talamanca‐Herz algebra Ap(G) of a locally compact group G. We show that for amenable groups, an order and algebra isomorphism of Figà‐Talamanca‐Herz‐algebras yields an isomorphism or anti‐isomorphism of the underlying groups.

Strain, Volume 61, Issue 1, February 2025.Abstract Biphasic flow propagating through a granular medium can be established as an unstable infiltration and can be precursors of nonnegligible deformations. Capturing such infiltration through the lens of a high‐resolution camera, full‐field strain maps are determined via digital image correlation (DIC).

Existence of a Periodic and Seasonal INAR Process
Journal of Time Series Analysis, Volume 45, Issue 6, Page 980-1005, November 2024.A spectral criterion involving the model parameters is given for the existence and uniqueness of a periodically correlated and seasonal non‐negative integer‐valued autoregressive process. The structure of the mean and covariance functions of the periodically stationary distribution of the model is derived using its implicit state‐space representation ...

Classification conjectures for Leavitt path algebras
Bulletin of the London Mathematical Society, Volume 56, Issue 10, Page 3011-3060, October 2024.Abstract The theory of Leavitt path algebras is intrinsically related, via graphs, to the theory of symbolic dynamics and C∗$C^*$‐algebras where the major classification programs have been a domain of intense research in the last 50 years. In this article, we gather together current lines of research in the classification of Leavitt path algebras ...

EEG functional connectivity as a Riemannian mediator: An application to malnutrition and cognition
Human Brain Mapping, Volume 45, Issue 7, May 2024.This study introduces a novel mediation analysis approach using EEG cross‐spectra to investigate whether malnourishment affects children's cognitive performance. The results indicate that brain function across delta, theta, alpha, and beta band frequencies mediates the impact of malnourishment on cognitive performance in specific brain regions ...

On the entropy and information of Gaussian mixtures
Mathematika, Volume 70, Issue 2, April 2024.Abstract We establish several convexity properties for the entropy and Fisher information of mixtures of centred Gaussian distributions. Firstly, we prove that if X1,X2$X_1, X_2$ are independent scalar Gaussian mixtures, then the entropy of tX1+1−tX2$\sqrt {t}X_1 + \sqrt {1-t}X_2$ is concave in t∈[0,1]$t \in [0,1]$, thus confirming a conjecture of Ball,
