Grothendieck group of module
WebMar 14, 2024 · Extriangulated categories give a simultaneous generalization of triangulated categories and exact categories. In this paper, we study silting subcategories of an extriangulated category. First, we show that a silting subcategory induces a basis of the Grothendieck group of an extriangulated category. Secondly, we introduce the notion of … WebOur main goal will be to completely characterize the Grothendieck group of a nonsingular algebraic curve in terms of its Picard group. We begin with a few de nitions. De nition 1.1. Let X be a noetherian scheme and let Cbe the category of coherent sheaves on X. Let Z[C] be the free abelian group generated by isomorphism classes [F] where F 2obC.
