The 1986 Seminar on Stochastic Processes was held at the University of
Virginia, Charlottesville, in March. It was the sixth seminar in a
continuing series of meetings which provide opportunities for
researchers to discuss current work in stochastic processes in an
informal atmosphere. Previous seminars were held at Northwestern
University, Evanston and the University of Florida, Gainesville. The
participants' enthusiasm and interest have resulted in stimulating and
successful seminars. We thank them for it, and we also thank those
participants who have permitted us to publish their research here. The
seminar was made possible through the generous support of the Office of
Naval Research (Contract # A86-4633-P) and the University of Virginia.
We are grateful for their support. The participants were welcomed to
Virginia by S. J. Taylor, whose store of energy and organizing talent
resulted in a wonderful reunion of researchers. We extend to him our
warmest appreciation for his efforts; his hospitality makes us hope that
we can someday return to Virginia for another conference. J. .
