    Ratio convergence rates for Euclidean first-passage percolation

    October 16, 2022




    Check out our new preprint Ratio convergence rates for Euclidean first-passage percolation: Applications to the graph infinity Laplacian on arXiv. We prove the first quantitative convergence rates for the graph infinity Laplace equation for length scales at the connectivity threshold. The code for the experiments can be found on our GitHub repository Percolation Convergence Rates.
