Variational problems for Airy processes

by Jeremy Quastel | University of Toronto
Time: 15:10  (Wednesday, Nov. 16, 2011)
Location: Stewart Library, Fields Institute, 222 College St.
Abstract:
We show how to compute the joint density of the max and argmax of the Airy_2 process minus a parabola. The argmax is a universal distribution governing the endpoint of directed random polymers in 1+1 dimensions.
