Lower bound for large local transversal fluctuations of Geodesics in Last Passage Percolation

Probability 2023-11-02 v1

Abstract

For exactly solvable models of planar last passage percolation, it is known that geodesics of length nn exhibit transversal fluctuations at scale n2/3n^{2/3} and matching (up to exponents) upper and lower bounds for the tail probabilities are available. The local transversal fluctuations near the endpoints are expected to be much smaller; it is known that the transversal fluctuation up to distance rnr \ll n is typically of the order r2/3r^{2/3} and the probability that the fluctuation is larger than tr2/3tr^{2/3} is at most Cect3Ce^{-ct^3}. In this note, we provide a short argument establishing a matching lower bound for this probability.
