Around 1955, the early studies of excessive functions of a Markov processcentered around two problems the relations between Brownian motion andNewtonian potential theory, and the behavior of the trajectories of the processX, as t approaches limits of infinity. The latter approach can be traced back to D. Blackwell 4,1955 who noticed the link between bounded invariant functions and the subsetsof G in which X, stays, from some finite time on, with positive probability.
