Kkj. Kinateder et P. Mcdonald, Variational principles for average exit time moments for diffusions in Euclidean space, P AM MATH S, 127(9), 1999, pp. 2767-2772
Let D be a smoothly bounded domain in Euclidean space and let X-t be a diff
usion in Euclidean space. For a class of diffusions, we develop variational
principles which characterize the average of the moments of the exit time
from D of a particle driven by X-t, where the average is taken overall star
ting points in D.
