Group algebras and semigroup algebras defined by permutation relations of fixed length

Ferran Cedo, Eric Jespers, Georg Klein

Let $H$ be a subgroup of $Sym_{n}$ , the symmetric group of degree $n$ . For a fixed integer $l \geq 2$ , the group $G$ presented with generators $x_{1}, x_{2}, \dots, x_{n}$ and with…

Finitely presented algebras defined by permutation relations of dihedral type

Ferran Cedo, Eric Jespers, Georg Klein

The class of finitely presented algebras over a field $K$ with a set of generators $a_{1}, \dots, a_{n}$ and defined by homogeneous relations of the form $a_{1}a_{2}\cdots a_{n} =…

Construction of a two unique product semigroup defined by permutation relations of quaternion type

Ferran Cedo, Eric Jespers, Georg Klein

For a regular representation $H \subseteq Sym_{n}$ of the generalized quaternion group of order $n = 4 k$ , with $k \geq 2$ , the monoid $S_{n} (H)$ presented with generators $a_1,a_2,…
