SummaryLetX andY be independent 3-dimensional Brownian motions,X(0)=(0,0,0),Y(0)=(1,0,0) and letpr=P(X[0,r] ⋂Y[0,r]=∅). Then the “non-intersection exponent”
$$mathop {lim }limits_{r o infty } - {{log p_{_r } } mathord{left/ {vphantom {{log p_{_r } } {log r}}}
ight. kern-
ulldelimiterspace} {log r}}$$
exists and is equal to a similar “non-intersection exponent” for random walks. Analogous results hold inR2 and for more than 2 paths.
