%0 Journal Article %T A non-displacable Lagrangian torus in T^*S^2 %A Peter Albers %A Urs Frauenfelder %J Mathematics %D 2006 %I arXiv %R 10.1002/cpa.20216 %X We show that the Lagrangian torus in the cotangent bundles of the 2-sphere obtained by applying the geodesic flow to the unit circle in a fibre is not displaceable by computing its Lagrangian Floer homology. The computation is based on a symmetry argument. %U http://arxiv.org/abs/math/0608356v2
