Grothendieck groups tri-exact category

WebFeb 1, 2014 · Abstract We define the Grothendieck group of an n -angulated category and show that for odd n its properties are as in the special case of n = 3, i.e. the triangulated case. In particular, its subgroups classify the dense and complete n -angulated subcategories via a bijective correspondence. WebGroup 8’s).
