9. Relaxing/perturbing integrable models


    1. Add remark

      Problem 9.1.

      Can one can relax the iid Bernoulli random walks that underlie the nontrivial structure in integrable models like PNG or TASEP, in formulas around the KPZ FP [MR4346267], [arXiv:2209.02643]? Another example includes the two-layer Gibbs measures (again, relying on simple random walks) that provide descriptions of stationary distributions in open particle systems [MR4777093].


        • Add remark

          Problem 9.2.

          Characterizing stochastic processes that one can put into formulas instead of random walks.
