Abstract/Media

Main talk:  Maher and Rivin independently showed that a random walk on the mapping class group gives a pseudo-Anosov map with probability tending to 1 in the length of the sample path. In joint work with J. Maher, we show that mapping classes along almost every infinite sample path are pseudo-Anosov with axis in the principal stratum of quadratic differentials. This provides an answer to a question of Kapovich-Pfaff.
