Topics in Cognitive Science, EarlyView., 2023 Abstract Over the past several decades, research in the cognitive sciences has foregrounded the importance of active bodies and their continuous dependence on the changing environment, strengthening the relevance of dynamical models. These models have been steadily developed within the ecological psychology approach to cognition, which arguably ...

Contributions to the essential dimension of finite and algebraic groups [PDF]
, 2010 Essential dimension, introduced by Joe Buhler and Zinovy Reichstein and in its most general form by Alexander Merkurjev is a measure of complexity of algebraic objects such as quadratic forms, hermitian forms, central simple algebras and étale algebras ...

Degrees of Faithful Irreducible Representations of Certain Metabelian Groups and a Question of Sim
, 2021 In this paper, we answer affirmatively a question of H S Sim on representations in characteristic $0$, for a class of metabelian groups. Moreover, we provide examples to point out that the analogous answer is no longer valid if the solvable group has derived length larger than 2.

On irreducible projective representations of finite groups [PDF]
Surveys in Mathematics and its Applications, 2009 The paper is a survey type article inwhich we present some results on irreducible projective representations offinite groups. Section 2 includes Curtis and Reiner's theorem inwhich is proved that a finite group has at most a finite number ofinequivalent ...

A lattice theoretic characterization for the existence of a faithful irreducible representation
International Journal of Group Theory, 2023 In a recent article S\'ebastien Palcoux formulated a sufficient condition on the subgroup lattice of a finite group $G$ that guarantees the existence of a faithful irreducible complex representation of $G$, and asked whether his condition is also necessary.

Exhausting families of representations and spectra of pseudodifferential operators [PDF]
, 2016 Families of representations of suitable Banach algebras provide a powerful tool in the study of the spectral theory of (pseudo)differential operators and of their Fredholmness.

On the extension of stringlike localised sectors in 2+1 dimensions [PDF]
, 2010 In the framework of algebraic quantum field theory, we study the category \Delta_BF^A of stringlike localised representations of a net of observables O \mapsto A(O) in three dimensions. It is shown that compactly localised (DHR) representations give rise

Differential posets and restriction in critical groups [PDF]
, 2019 In recent work, Benkart, Klivans, and Reiner defined the critical group of a faithful representation of a finite group $G$, which is analogous to the critical group of a graph.

Faithful Irreducible Representations of Metacyclic Groups
Journal of Algebra, 1994 The author proves some results on the representations of metacyclic groups. One of these is the following: A metacyclic group has a faithful irreducible representation over a field \(\mathbb{F}\) is and only if the center of the group is cyclic and the characteristic of \(\mathbb{F}\) does not divide the order of the Fitting group. As an application of
