    On the Enumeration of Finite L-Algebras
    (Oberwolfach : Mathematisches Forschungsinstitut Oberwolfach, 2022) Dietzel, Carsten; Menchón, Paula; Vendramin, Leandro
    We use Constraint Satisfaction Methods to construct and enumerate finite L-algebras up to isomorphism. These objects were recently introduced by Rump and appear in Garside theory, algebraic logic, and the study of the combinatorial Yang-Baxter equation. There are 377322225 isomorphism classes of L-algebras of size eight. The database constructed suggest the existence of bijections between certain classes of L-algebras and well-known combinatorial objects. On the one hand, we prove that Bell numbers enumerate isomorphism classes of finite linear L-algebras. On the other hand, we also prove that finite regular L-algebras are in bijective correspondence with infinite-dimensional Young diagrams.
