The topics class Math 7853 this
          spring will be on "curve counting". I
          will follow the book
            
            Erlandsson-Souto: Mirzakhani's curve counting and geodesic
            currents
            
          The book presents a proof of (a generalization of) a
          theorem of Maryam
          Mirzakhani that gives an asymptotic count of the number of
          curves on a
          surface in the same mapping class group orbit as a given
          curve. We'll
          spend a fair bit of time on the background, most of it from
          the
          Thurston school of surface geometry: measured laminations,
          currents, train
          tracks. For a few weeks I'll pretend to be Jon Chaika and talk
          about ergodic theory.
          
          Prerequisites: You should be comfortable with measure theory
          as in
          Math 6210 and with the basic hyperbolic geometry.
