On existence of canonical $G$-bases
, 2017 We describe a general method for expanding a truncated G-iterative Hasse-Schmidt derivation, where G is an algebraic group.

ALGEBRAIC QUANTUM PERMUTATION GROUPS [PDF]
Asian-European Journal of Mathematics, 2008 We discuss some algebraic aspects of quantum permutation groups, working over arbitrary fields. If đ is any characteristic zero field, we show that there exists a universal cosemisimple Hopf algebra coacting on the diagonal algebra đn: this is a refinement of Wang's universality theorem for the (compact) quantum permutation group.

Advanced Intelligent Discovery, EarlyView.This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of realâworld data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

Evolutionary dynamics on a regular networked structured and unstructured multiâpopulation
International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract In this paper, we study collective decisionâmaking in a multiâpopulation framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.

Wonderful compactifications of Bruhat-Tits buildings [PDF]
Ăpijournal de GĂ©omĂ©trie AlgĂ©brique, 2017 Given a split semisimple group over a local field, we consider the maximal Satake-Berkovich compactification of the corresponding Euclidean building. We prove that it can be equivariantly identified with the compactification which we get by embedding the

Advanced Intelligent Systems, EarlyView.This study introduces a framework that combines graph neural networks with causal inference to forecast recurrence and uncover the clinical and pathological factors driving it. It further provides interpretability, validates risk factors via counterfactual and interventional analyses, and offers evidenceâbased insights for treatment planning ...

The build up construction for codes over a non-commutative non-unitary ring of order 9
AIMS MathematicsThe build-up method is a powerful class of propagation rules that generate self-dual codes over finite fields and unitary rings. Recently, it was extended to non-unitary rings of order four to generate quasi self-dual codes.

The group of automorphisms of a real rational surface is n-transitive
, 2008 Let X be a rational nonsingular compact connected real algebraic surface. Denote by Aut(X) the group of real algebraic automorphisms of X. We show that the group Aut(X) acts n-transitively on X, for all natural integers n. As an application we give a new

Review of Memristors for InâMemory Computing and Spiking Neural Networks
Advanced Intelligent Systems, EarlyView.Memristors uniquely enable energyâefficient, brainâinspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...
