Pluricanonical Cohomology Across Flips

Pluricanonical Cohomology Across Flips A flip can be thought of as a diagram X−→X←X+ of complex threefolds satisfying some conditions. One often thinks of a flip as being in two parts: the first part, X−→X, is the given, while the second, X←X+, is the unknown. I calculate cohomological properties of the canonical classes, K−=KX− and so on, and in particular properties of the function http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of the London Mathematical Society Wiley
