摘要：
In standard first-passage percolation on Z(d) (with d greater than or equal to 2), the time-minimizing paths from a point to a plane at distance L are expected to have transverse fluctuations of order L(xi). It has been conjectured that xi(d) greater than or equal to 1/2 with the inequality strict (superdiffusivity) at least for low d and with xi(2)= 2/3. We prove (versions of) xi(d) greater than or equal to 1/2 for all d and xi(2) greater than or equal to 3/5.
