DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Freemath/5/"
 >Displacement energy of Lagrangian 3-spheres</a>\nby Yuhan Sun (Stony Broo
 k) as part of Free Mathematics Seminar\n\n\nAbstract\nWe study local and g
 lobal Hamiltonian dynamical behaviours of some Lagrangian submanifolds nea
 r a Lagrangian sphere S in a symplectic manifold X. When dim S = 2\, we sh
 ow that there is a one-parameter family of Lagrangian tori near S\, which 
 are nondisplaceable in X. When dim S = 3\, we obtain a new estimate of the
  displacement energy of S\, by estimating the displacement energy of a one
 -parameter family of Lagrangian tori near S.\n
