Starting from one-point tail bounds, we establish an upper tail large deviation principle for the directed landscape at the metric level. Metrics of finite rate are in one-to-one correspondence with measures supported on a set of countably many paths, and the rate function is given by a certain Kruzhkov entropy of these measures. As an application of our main result, we prove a large deviation principle for the directed geodesic.

  1. An upper tail field of the KPZ fixed point

    math.PR 2025-01 conditional novelty 8.0 of 10

    A newly constructed 'upper tail field' is the local limit of the KPZ fixed point near a conditioned large value, interpolating between Brownian and KPZ scaling regimes.

  2. Large deviations of geodesic midpoint fluctuations in last-passage percolation with general i.i.d. weights

    math.PR 2025-02 conditional novelty 6.0 of 10

    For general i.i.d. weights, the midpoint of the geodesic between (0,0) and (n,n) lying at position n/2+tn has probability e^{-2nJ_t(μ0)+o(n)}.
