Webinjective function of N. It implies that all odd powers of Dehn twists ˝N are distinct, and so are all powers of Dehn twists ˝N. Note that for nodd, the Brieskorn manifolds ( N;2;:::;2) are all non-di eomorphic. Furthermore, such Dehn twists can be constructed for any symplectic manifold containing a Lagrangian sphere. WebOur proof uses a relationship between Heegaard Floer homology and the dynamics of surface diffeomorphisms. This is based on joint work with Yi Ni and Steven Sivek. ... mapping class group elements, symplectic Dehn twists, spherical twists in derived categories, or flop functors for 3-folds.
