Tails of the endpoint distribution of directed polymers

arXiv:1203.2907 · doi:10.1214/12-AIHP525

Abstract

We prove that the random variable $\ct=\argmax_{t\in\rr}\{\aip(t)-t^2\}$ has tails which decay like . The distribution of $\ct$ is a universal distribution which governs the rescaled endpoint of directed polymers in 1+1 dimensions for large time or temperature.
