Skew braces: a brief survey
Leandro Vendramin
Our primary focus is on the theory of skew braces, specifically exploring their connection with combinatorial solutions to the Yang-Baxter equation. Skew braces have recently emerg…
On computing finite index subgroups of PSL(2,Z)
Nicolás Mayorga Uruburu, Ariel Pacetti, Leandro Vendramin
We present a method to compute finite index subgroups of . Our strategy follows Kulkarni's ideas, the main contribution being a recursive method to compute bival…
Finite-dimensional Nichols algebras of simple Yetter-Drinfeld modules (over groups) of prime dimension
I. Heckenberger, E. Meir, L. Vendramin
Over fields of characteristic zero, we determine all absolutely irreducible Yetter-Drinfeld modules over groups that have prime dimension and yield a finite-dimensional Nichols alg…
Schur covers of skew braces
T. Letourmy, L. Vendramin
We develop the theory of Schur covers of finite skew braces. We prove the existence of at least one Schur cover. We also compute several examples. We prove that different Schur cov…
