A Hsu.Robbins.Erd.s strong law in first-passage percolation

Large deviations in the context of first-passage percolation was first studied in the early 1980s by Grimmett and Kesten, and has since been revisited in a variety of studies. However, none of these studies provides a precise relation between the existence of moments of polynomial order and the decay of probability tails. Such a relation is derived in this paper, and is used to strengthen the conclusion of the shape theorem. In contrast to its one-dimensional counterpart.the Hsu.Robbins.Erd.s strong law.this strengthening is obtained without imposing a higher-order moment condition.
