摘要:In this talk, we will examine the definitions of Hall algebras, which include abelian categories, exact categories, and triangular categories. We proceed to define the Hall algebra associated with an extriangulated category. Let An be the linearly oriented quiver of type A. With this definition, we show that there exists an Hall algebra isomorphism between the extriangulated categories Mn+1 and Fn, where Mn+1 and Fn are the two extriangulated categories corresponding to the representation category of An+1 and the morphism category of projective representations of An, respectively.
