We show existence and uniqueness of solutions for a class of nonlinear
evolution equations with gradient coupled noise. Our results are obta
ined by using a simple transformation relating the equation under cons
ideration to an underlying deterministic partial differential equation
. Both the It (o) over cap and the Stratonovich conventions are treate
d. Several examples show that the properties of solutions for It (o) o
ver cap equations can differ significantly from those of Stratonovich
equations.
