Empirical measures, geodesic lengths, and a variational formula in
first-passage percolation.
We consider the standard first-passage percolation model on Z^d, in
which each edge is assigned an i.i.d. non-negative weight, and the
passage time between any two points is the smallest total weight of a
nearest-neighbor path between them. Our primary interest is in the
empirical measures of edge-weights observed along geodesics from 0 to
ne_1. For various dense families of edge-weight distributions, we prove
that these measures converge weakly to a deterministic limit as n tends
to infinity. These families include arbitrarily small
L^infty-perturbations of any given distribution, as well as almost every
finitely supported distribution. Analogous results hold for
e_1-directed infinite geodesics. Our methodology is driven by a new
variational formula for the time constant, which requires no assumptions
on the edge-weight distribution. Incidentally, this variational
approach allows us to recover and extend a recent result of Krishnan,
Rassoul-Agha, and Seppäläinen regarding the convergence of geodesic
lengths.
