On checkable codes in group algebras [PDF]
Journal of Algebra and its Applications, 2019 We classify, in terms of the structure of the finite group G, all group algebras KG for which all right ideals are right annihilators of principal left ideals.

A smooth version of Johnson’s problem on derivations of group algebras [PDF]
Sbornik: Mathematics, 2018 We give a description of the algebra of outer derivations of the group algebra of a finitely presented discrete group in terms of the Cayley complex of the groupoid of the adjoint action of the group. This problem is a smooth version of Johnson’s problem

Group Algebra Modules. II [PDF]
Canadian Journal of Mathematics, 1967 The present paper began as a natural outgrowth of our first paper, where we characterized the module homomorphisms from group algebras into a fairly restrictive class of group algebra modules. We now investigate module homomorphisms from group algebras into a more general class of group algebra modules.

New Partial Symmetries from Group Algebras for Lepton Mixing
Advances in High Energy Physics, 2020 Recent stringent experiment data of neutrino oscillations induces partial symmetries such as Z2 and Z2×CP to derive lepton mixing patterns. New partial symmetries expressed with elements of group algebras are studied.

Group algebras and coding theory [PDF]
São Paulo Journal of Mathematical Sciences, 2014 Group algebras have been used in the context of Coding Theory since the beginning of the latter, but not in its full power. The article of Ferraz and Polcino Milies entitled Idempotents in group algebras and minimal abelian codes (Finite Fields Appl 13(2)

Free probability on Hecke algebras and certain group C^{*}-algebras induced by Hecke algebras [PDF]
Opuscula Mathematica, 2016 In this paper, by establishing free-probabilistic models on the Hecke algebras \(\mathcal{H}\left(GL_{2}(\mathbb{Q}_{p})\right)\) induced by \(p\)-adic number fields \(\mathbb{Q}_{p}\), we construct free probability spaces for all primes \(p\).

Monothetic algebraic groups [PDF]
Journal of the Australian Mathematical Society, 2007 AbstractWe call an algebraic group monothetic if it possesses a dense cyclic subgroup. For an arbitrary field k we describe the structure of all, not necessarily affine, monothetic k-groups G and determine in which cases G has a k-rational generator.

Nuclearity of semigroup C*-algebras and the connection to amenability [PDF]
, 2012 We study C*-algebras associated with subsemigroups of groups. For a large class of such semigroups including positive cones in quasi-lattice ordered groups and left Ore semigroups, we describe the corresponding semigroup C*-algebras as C*-algebras of ...

On Deterministic and Absorbing Algebras of Binary Formulas of Polygonometrical Theories
Известия Иркутского государственного университета: Серия "Математика", 2017 Algebras of distributions of binary isolating and semi-isolating formulas are derived structures for a given theory. These algebras reflect binary links between realizations of 1-types defined by formulas of the initial theory.
