“Frobenius orbit categories and cluster algebras”

speaker: Alfredo Najera Chavez (Université Paris Diderot - Paris 7 )

abstract: We study orbit categories associated to Frobenius categories in a general framework. We apply our main result in the context of Nakajima categories associated to Dynkin quivers to obtain explicit categorifications of families of cluster algebras with coefficients. In particular, we obtain a 2-Calabi-Yau realization of all skew-symmetric cluster algebras of finite type with universal coefficients.
