First, we show that a certain sequence of idempotents e0; e1; : : : ; e l in a ring A deΓΏnes a tilting complex P β’ for A of term length l + 1 and that there exists a sequence of rings B0 = A; B1; : : : ; B l = End K(Mod-A) (P β’ ) such that for any 0 6 i Β‘ l, Bi+1 is the endomorphism ring of a tiltin
