New construction of symplectomorphisms
Apparaît dans la collection : Giroux 60 - Convexity in contact and symplectic topology
We introduce two new constructions of compactly supported symplectomorphisms of Weinstein 4-manifolds: Lagrangian translations' andnodal slide recombinations'. These are natural from the perspective of mirror symmetry. After an overview of the constructions and their properties, the talk will focus on describing the maps in the first non-trivial cases. Joint work with Paul Hacking.
