This volume consists of 24 papers submitted for publication
by the invited speakers of the IFIP International Conference
on Stochastic Partial Differential Equations and their Ap-
plications. Most of them are research papers, however, a few
surveys written by world renowed experts are also included.
The aim of the conference was to bring together mathematici-
ans, physicists and engineers representing academic as well
as industrial fields, interested in the theory and applica-
tions of SPDE's. The field of SPDE's is one of the most dy-
namically developing areas at the cross roads of several
sciences. It is especially attractive for many because of
its interdisciplinary character and enormous richness ofal-
ready existing as well as potential applications. There were
about one hundred participants registered for the conferen-
ce. With rare exceptions, all of the most active researchers
in the field of SPDE's throughout the world were present at
the conference. The main topics for discussion at the confe-
rence were: non-linear SPDE's and Markov property for random
fields, modern stochastic calculuses, numerical and asympto-
tic methods for SPDE's, applications of SPDE's with emphasis
onnon-linear filtering, stochastic control and statistical
fluid dynamics.
