The 1992 Seminar on Stochastic Processes was held at the Univer- sity of
Washington from March 26 to March 28, 1992. This was the twelfth in a
series of annual meetings which provide researchers with the opportunity
to discuss current work on stochastic processes in an informal and
enjoyable atmosphere. Previous seminars were held at Northwestern
University, Princeton University, University of Florida, University of
Virginia, University of California, San Diego, University of British
Columbia and University of California, Los An- geles. Following the
successful format of previous years, there were five invited lectures,
delivered by R. Adler, R. Banuelos, J. Pitman, S. J. Taylor and R.
Williams, with the remainder of the time being devoted to informal
communications and workshops on current work and problems. The
enthusiasm and interest of the participants cre- ated a lively and
stimulating atmosphere for the seminar. A sample of the research
discussed there is contained in this volume. The 1992 Seminar was made
possible through the support of the National Science Foundation, the
National Security Agency, the Institute of Mathematical Statistics and
the University of Washing- ton. We extend our thanks to them and to the
publisher Birkhauser Boston for their support and encouragement. Richard
