GIM and Elliptic Lie algebras via Ringel--Hall Lie algebras
Changjian Fu, Zhanhong Liang, Ming Lu
For any symmetrizable generalized intersection matrix (GIM) , we construct an acyclic valued quiver endowed with an involution . Let be the bou…
Homological rigidity of quiver representations over
Changjian Fu, Liang Yang, Zhiyuan Zeng
We establish a homological rigidity phenomenon for the category of representations of quivers over the virtual field , which is inherently non-additive and does not a…
On endomorphism algebras of silting complexes over hereditary abelian categories
Wei Dai, Changjian Fu, Liangang Peng
Let be the class of finite-dimensional algebras isomorphic to endomorphism algebras of silting complexes over hereditary abelian categories. It is proved that the cla…
A correspondence between additive and monoidal categorifications with application to Grassmannian cluster categories
Karin Baur, Changjian Fu, Jian-rong Li
Building on work of Derksen-Fei and Plamondon, we formulate a conjectural correspondence between additive and monoidal categorifications of cluster algebras, which reveals a new co…
