摘要：

We classify for which a, b, c, and k there exists complexes O-Pk(-1)(a) -->(alpha) O-Pk(b) -->(beta) O-Pk(1)(c) with alpha injective and beta surjective. Furthermore we show that when it exists, we may assume that alpha degenerates in P-k in expected codimension, which is b - a - c + 1. We give applications to instanton bundles, space curves, and surfaces in P-4.
