Persistence probabilities for an integrated random walk bridge

Probability 2015-02-24 v1

Abstract

We prove that an integrated simple random walk, where random walk and integrated random walk are conditioned to return to zero, has asymptotic probability n1/2n^{-1/2} to stay positive. This question is motivated by so-called random polymer models and proves a conjecture by Caravenna and Deuschel.
