Title: A Numerical Method for Wick-Stochastic Partial Differential
-----
Equations


Abstract:
---------
In this talk we present two numerical techniques for solving stochastic
partial differential equations. The stochasticity in these equations can
be included as random coefficients in the differential operators or as
stochastic excitations in the forcing terms. For linear and semi-linear
equations we present results obtained using a coupled spectral
Galerkin-characteristic method while a method of lines is used for the
case of nonlinear equations. Computational results will be shown for
stochastic Burgers and incompressible Navier-Stokes problems, and also 
for a replicator model in catalyzed RNA-like polymers.
