The 1987 Seminar on Stochastic Processes was held at Princeton
University, March 26 through March 28, 1987. It was the seventh seminar
in a continuing series of meetings which provide opportunities for
researchers to discuss current work in stochastic processes in an
informal and enjoyable atmosphere. Previous seminars were held at
Northwestern University, Evanston; University of Florida, Gainesville:
and University of Virginia, Charlottesville. The success of these
seminars has been due to the interest and enthusiasm of probabilists in
the United States and abroad. Many of the participants have allowed us
to pUblish the results of their re- search in this volume. The editors
hope that the reader will be able to sense some of the excitement
present in the seminar by reading these articles. This year's invited
participants included M. Aizenman, B. Atkinson, R. M. Blumenthal, C.
Burdzy, D. Burkholder, R. Carmona, K. L. Chung, M. Cranston, C.
Dellacherie, J. D. Deuschel, N. Dinculeanu, Gundy, P. Hsu, E. B. Dynkin,
