Representations of Modular Skew Group Algebras [PDF]

Transactions of the American Mathematical Society, 2014
In this paper we study representations of skew group algebras $\Lambda G$, where $\Lambda$ is a connected, basic, finite-dimensional algebra (or a locally finite graded algebra) over an algebraically closed field $k$ with characteristic $p \geqslant 0 ...

Modular representations of Loewy length two [PDF]

International Journal of Mathematics and Mathematical Sciences, 2003
Let G be a finite p-group, K a field of characteristic p, and J the radical of the group algebra K[G]. We study modular representations using some new results of the theory of extensions of modules.

Ordinary representations and modular forms [PDF]

Proceedings of the National Academy of Sciences, 1997
Let \(p\) be a prime, and fix on embedding of \(\overline{\mathbb{Q}}\) into \(\overline{\mathbb{Q}}_p\). Let \(f\) be a new form of weight \(k\geq 2\), level \(N\) and character \(\psi\). Let \(\rho_f: \text{Gal} (\overline{\mathbb{Q}}/ \mathbb{Q})\to \text{GL}_2 (\overline{\mathbb{Q}}_p)\) be a continuous representation attached to \(f\) by Eichler ...

Coxeter Orbits and Modular Representations [PDF]

Nagoya Mathematical Journal, 2006
AbstractWe study the modular representations of finite groups of Lie type arising in the cohomology of certain quotients of Deligne-Lusztig varieties associated with Coxeter elements. These quotients are related to Gelfand-Graev representations and we present a conjecture on the Deligne-Lusztig restriction of Gelfand-Graev representations. We prove the

Modularity of Galois representations [PDF]

Journal de théorie des nombres de Bordeaux, 2003
This paper is essentially the text of the author’s lecture at the 2001 Journées Arithmétiques. It addresses the problem of identifying in Galois-theoretic terms those two-dimensional, p-adic Galois representations associated to holomorphic Hilbert modular newforms.

Fermion mass hierarchies, large lepton mixing and residual modular symmetries

Journal of High Energy Physics, 2021
In modular-invariant models of flavour, hierarchical fermion mass matrices may arise solely due to the proximity of the modulus τ to a point of residual symmetry.

Seven Small Simple Groups Not Previously Known to Be Galois Over $\mathbb{Q}$

Mathematics, 2022
In this note we realize seven small simple groups as Galois groups over Q. The technique that we employ is the determination of the images of Galois representations attached to modular and automorphic forms, relying in two cases on recent results of ...

Modular representations with additional conditions of the semigroup T2 × S2 .

Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017
We describe matrix problems of nite type associated with modular representations of the direct product of the symmetric semigroup and symmetric group of degree 2. In each case we obtain an explicit classication of the corresponding representations.

Modular A 5 symmetry for flavour model building

Journal of High Energy Physics, 2019
In the framework of the modular symmetry approach to lepton flavour, we consider a class of theories where matter superfields transform in representations of the finite modular group Γ5 ≃ A 5.
