Exceptional sequences in the derived category of a gentle algebra
Wen Chang, Sibylle Schroll
In this paper, using the correspondence of gentle algebras and dissections of marked surfaces, we study full exceptional sequences in the perfect derived category …
A geometric realization of silting theory for gentle algebras
Wen Chang, Sibylle Schroll
A gentle algebra gives rise to a dissection of an oriented marked surface with boundary into polygons and the bounded derived category of the gentle algebra has a geometric interpr…
Quivers with potentials for Grassmannian cluster algebras
Wen Chang, Jie Zhang
We consider (iced) quiver with potential associated to a Postnilov Diagram and prove the mutation of the quiver with potential $(\bare{Q}(D), F…
Quantum affine algebras and Grassmannians
Wen Chang, Bing Duan, Chris Fraser +1
We study the relation between quantum affine algebras of type A and Grassmannian cluster algebras. Hernandez and Leclerc described an isomorphism from the Grothendieck ring of a ce…
A note on cluster automorphism groups
Wen Chang, Ralf Schiffler
We conjecture a characterization of a cluster automorphism as an algebra homomorphism from the cluster algebra to itself that restricts to a bijection between two clusters. This fo…
