Hyperbolicity of Semigroup Algebras II
E. Iwaki, E. Jespers, S. O. Juriaans +1
In 1996 Jespers and Wang classified finite semigroups whose integral semigroup ring has finitely many units. In a recent paper, Iwaki-Juriaans-Souza Filho continued this line of re…
Finitely presented algebras and groups defined by permutation relations
F. Cedo, E. Jespers, J. Okninksi
The class of finitely presented algebras over a field with a set of generators and defined by homogeneous relations of the form $a_{1}a_{2}... a_{n} =a_{σ(a)…
Antisymmetric Elements in Group Rings II
O. Broche, E. Jespers, C. Polcino Milies +1
Let be a commutative ring, a group and its group ring. Let $\vp : RG\to RG$ denote the -linear extension of an involution $\vp$ defined on . An element in $R…
Semigroup algebras of submonoids of polycyclic-by-finite groups and maximal orders
Isabel Goffa, Eric Jespers, Jan Okninski
Necessary and sufficient conditions are given for a prime Noetherian algebra K[S] of a submonoid S of a polycyclic-by-finite group G to be a maximal order. These conditions are ent…
Group identities on the units of algebraic algebras with applications to restricted enveloping algebras
Eric Jespers, David Riley, Salvatore Siciliano
An algebra is called a GI-algebra if its group of units satisfies a group identity. We provide positive support for the following two open problems. 1. Does every algebraic GI-alge…
Quadratic algebras of skew type and the underlying semigroups
T. Gateva-Ivanova, Eric Jespers, Jan Okninski
We consider algebras over a field K defined by a presentation K <x_1,..., x_n : R >, where consists of n choose 2 square-free relations of the form x_i x_j = x_k x_l with every…
