Title:A non-displacable Lagrangian torus in T*S^2
Seminar:Symplectic Topology Seminar
Speaker:Peter Albers (New York University)
Abstract:
Leonid Polterovich exhibited a beautiful Lagrangian torus in T*S2 and asked if this torus is Hamiltonianly displaceable. In joint work with Urs Frauenfelder we prove that the Lagrangian Floer homology does not vanish, indeed equals the singular homology of the torus. In particular, this gives a negative answer to Polterovich's question. In the talk I will describe the construction of the Lagrangian torus and present the computation of the Lagrangian Floer homology which is based on an symmetry argument.
