The main thrust of this research is to study three                         dimensional algebraic varieties (threefolds).  The Principal                    Investigator's past work will be continued on questions on                      algebraic fibre spaces together with the applications to the                    classification of threefolds.  The current work also concerns the               structure of birational mappings between threefolds, especially                 the codimension-two algebraic surgerys called "flips" and "flops"               which are now understood to be a central feature of birational                  maps in dimension three.  A potential application of all of this                is to produce a geometrically meaningful compactification of                    moduli spaces of surfaces via the study of the fibration of the                 threefold obtained from a one-parameter family of surfaces,                     especially curvature properties of that fibration.
