We investigate the group Pic(DM) of isomorphism classes of invertible objects in the derived category of O-modules for a commutative unital ringed Grothendieck topos (E;O) with enough points. When the ring Op has connected prime ideal spectrum for all points p of E we show that Pic(D M ) is naturall
Given a finite dimensional hereditary algebra ฮ over a finite field k, in the derived category D b (ฮ) we obtain some formulae on Hall numbers associated to triangles. Using them we prove that, for any tilted algebra ฮ of ฮ, there is an embedding of the twisted Ringel-Hall algebra of ฮ into the Drin
