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 Web1.From last time: note that the Dehn Twist can be made into a compactly di eomorphism, i.e. the twist is accomplished in a nite amount of time. This means that we can \implant" the twist in other surfaces, e.g. the torus which locally looks like S1 [0;1], which gives a symplectomorphism on most surfaces which is not of the form T’= d’
