Hind August 19, 2005 In this paper we answer a question raised in [8] as to whether, at least in a simple situation, symplectic Dehn twists provide the only method of construct-ing symplectically knotted Lagrangian spheres in a symplectic 4-manifold. We flrst recall the arrangement from [8].

WebKronheimer's argument: Small resolutions and Dehn twists. I want to amplify an expository argument I gave in a recent lecture which shows that the squared Dehn twist on a symplectic 4-manifold is smoothly isotopic to the identity map. This is an old argument of Kronheimer and I only managed to sketch it hurriedly in the lecture. http://dynamiccomposites.com/

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. The hard part of studying the symplectic isotopy problem is how to WebMay 6, 2024 · On the other hand, monodromy ideas motivate representations of generalized braid groups as various flavors of geometric automorphisms -- for instance, as (framed) mapping class group elements, symplectic Dehn twists, spherical twists in derived categories, or flop functors for 3-folds.
