WebLet us recall the deﬁnition of a full exceptional collection in a k-linear triangulated category T. Deﬁnition 1. An object Ein T is said to be exceptional if Ext•(E,E)=k. Deﬁnition 2. A sequence of objects E 1,...,E m in T is called an exceptional collection if all E i are exceptional and Ext•(E i,E j)=0for all i>j. A collection (E 1 ... WebSep 7, 2011 · In the case of derived categories, this requires also the tensor structure. We start with the classical case of the category of coherent sheaves (after Gabriel).

Webalgebraic geometry - typically, with derived categories of sheaves on a given scheme. It is well-known that, from a theoretical point of view, triangulated categories are far from being well-behaved: there is no sensible way to define a "triangulated category of triangulated functors between triangulated categories" or a tensor product. Webtaking the corresponding derived category. A t-structure allows you to make the reverse construction i.e. it gives you an abelian category from a triangulated category.
