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 ...
Homological algebra and representation theory form a powerful confluence in modern mathematics. Homological algebra provides a framework for analysing algebraic structures via chain complexes, ...
