WebIn general, a triangulated category may have three types of nice gadgets: strong exceptional collection, exceptional collection, tilting object. Number 1 gives both 2 and 3. 2 or 3 do not give each other or 1. Each of these gadgets gives you a realization of your category as derived representations of a directed quiver (with relations), WebTwo rings A and B are said to be derived Morita equivalent if the derived categories Db(Mod A) and Db(Mod B) are equivalent. ... The complex T is called a tilting complex.%When B = A the isomorphism classes of tilting complexes T form the derived Picard group DPic(A).
