Dynamics of composite symplectic dehn twists
Webthat there are symplectic manifolds for which the answer is positive; in fact, a large class of symplectic four-manifolds is shown to have this property. This result is the consequence of the study of a special class of symplectic automorphisms, called generalized Dehn twists.

WebNov 5, 2024 · Abstract. This paper introduces a new Lagrangian surgery construction that generalizes Lalonde–Sikorav and Polterovich’s well-known construction, and combines this with Biran and Cornea’s Lagrangian cobordism formalism. With these techniques, we build a framework which both recovers several known long exact sequences (Seidel’s exact ...

WebFeb 20, 2014 · A Dehn twist is an operation so we need a before an after. In the picture below imagine the top and bottom of each cylinder are identified so that the end points of the red curve are identified, the end points of the blue curve are identified, and there is no twisting of the red curve on the left, e.g the red and blue curves are unlinked. 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.

Proof. First note ([6] or [1]) that if C is any Dehn twist about a non-bounding curve in F, then there is an element a of M(F) such tha1 =t aEa' C. It follows tha2 belongt C s to N.
