DESCRIPTION:In this talk\, we will explain how to construct closed Lagrang
 ian submanifolds in mirror quintic threefolds using tropical curves and th
 e toric degeneration technique. As an example\, we will illustrate how the
  corresponding Lagrangians look like for tropical curves that contribute t
 o the Gromov-Witten invariant of the line class of the quintic threefold. 
 We will also show that multiplicity of a tropical curve\, in this symplect
 ic setting\, will be realized as the order of the torsion the first homolo
 gy group of the Lagrangian. This is a joint work with Helge Ruddat.\n
