Cluster algebras constitute a robust framework at the interface of algebra, combinatorics and geometry. Since their introduction, they have provided fertile ground for understanding total positivity, ...

In my talk, I will introduce an example of a multiplier Hopf algebroid (object recently introduced by T. Timmermann and A. Van Daele) generalizing the transformation groupoids which is inspired by the ...

Semigroups of transformations and endomorphisms have emerged as powerful algebraic frameworks to elucidate the underlying structures of graphs. By harnessing the principles of semigroup theory, ...
