22 p, 445.7 KB Growth alternative for Hecke-Kiselman monoids / Meçel, Arkadiusz (University of Warsaw (Polònia). Institute of Mathematics) ; Okniński, Jan (University of Warsaw (Polònia). Institute of Mathematics)
The Gelfand-Kirillov dimension of Hecke-Kiselman algebras defined by oriented graphs is studied. It is shown that the dimension is infinite if and only if the underlying graph contains two cycles connected by an (oriented) path. [...]

25 p, 363.8 KB Nilpotent groups of class three and braces / Cedó, Ferran (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Jespens, Eric (Vrije Universiteit Brussel. Department of Mathematics) ; Okniński, Jan (Warsaw University (Polònia). Institute of Mathematics)
New constructions of braces on finite nilpotent groups are given and hence this leads to new solutions of the Yang-Baxter equation. In particular, it follows that if a group G of odd order is nilpotent of class three, then it is a homomorphic image of the multiplicative group of a finite left brace (i. [...]

20 p, 366.0 KB Conjugacy classes of left ideals of a finite dimensional algebra / Meçel, Arkadiusz (Warsaw University (Polònia). Institute of Mathematics) ; Okniński, Jan (Warsaw University (Polònia). Institute of Mathematics)
Let A be a finite dimensional unital algebra over a field K and let C(A) denote the set of conjugacy classes of left ideals in A. It is shown that C(A) is finite if and only if the number of conjugacy classes of nilpotent left ideals in A is finite. [...]

22 p, 215.4 KB Faithful linear representations of bands / Cedó, Ferran (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Okniński, Jan (Warsaw University (Polònia). Institute of Mathematics)
A band is a semigroup consisting of idempotents. It is proved that for any field K and any band S with finitely many components, the semigroup algebra K [S] can be embedded in upper triangular matrices over a commutative K-algebra. [...]
