WebWe characterize tilting sheaves as those sheaves M ∈ coh ( X) that lead to an equivalence φ: D b (coh ( X ))→ D b (mod ( B )) with φ ( M )= B, where B is the endomorphism algebra of M. An induced comparison theorem interrelates directly certain subcategories of coh ( X) and mod ( B ), respectively. For a weighted projective space X, these ...

WebA partition of an integer n is a representation of n as a sum of positive integers where the order of the summands is considered irrelevant. Thus we see that there are five partitions of the integer 4, namely 4, 3+1, 2+2, 2+1+1, 1+1+1+1. The partition function p (n) denotes the number of partitions of n. Thus p (4) = 5. dutch healthcare insuranceWebAs a consequence, it provides an intrinsic new proof to the equivalence of M.
