Derived categories and their uses
Webderived category originally appeared as a technical tool needed for generalizing Poincar´e and Serre duality to relative settings, lately (especially since Kontsevich’s statement of Homological Mirror Symmetry [19]) derived categories have taken a life of their own. 1.2.
