DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDS/65/">Tor
 ic geometry and tropical trigonometry</a>\nby Grigory Mikhalkin (Universit
 y of Geneva) as part of Geometry and Dynamics seminar\n\n\nAbstract\nToric
  varieties were constructed as algebraic varieties about 50 years ago\, \n
 and also as symplectic varieties about 40 years ago. The two constructions
  \nare dual to each other\, but are based on the same geometry in R^n. Sym
 metries \nin this geometry are linear transformations given by invertible 
 n-by-n \nmatrices with integer coefficients\, as well as all translations.
  This makes \nthe notion of a tangent integer vector as well as a notion o
 f tropical curve \nwell-defined. The talk will review basic constructions 
 with a focus on \ntropical triangles that underlie some recent progress in
  symplectic embedding \nproblems.\n
