Recollements of extriangulated categories
Li Wang, Jiaqun Wei, Haicheng Zhang
We give a simultaneous generalization of recollements of abelian categories and triangulated categories, which we call recollements of extriangulated categories. For a recollement…
Semibricks in extriangulated categories
Li Wang, Jiaqun Wei, Haicheng Zhang
Let be a semibrick in an extriangulated category . Let be the filtration subcategory generated by . We give a one-to-one corre…
Idempotent completion of extriangulated categories
Li Wang, Jiaqun Wei, Haicheng Zhang +1
Extriangulated categories were introduced by Nakaoka and Palu as a simultaneous generalization of exact categories and triangulated categories. In this paper, we show that the idem…
Quantum cluster characters of Hall algebras revisited
Changjian Fu, Liangang Peng, Haicheng Zhang
Let be a finite acyclic valued quiver. We define a bialgebra structure and an integration map on the Hall algebra associated to the morphism category of projective representati…
