An Estimation Problem for Quasilinear Stochastic Partial Differential Equations
Authors:Ibragimov  I. A.
Abstract:A problem of estimating a functional parameter theta(x) and functionals PHgr(theta) based on observation of a solution u epsi(t, x) of the stochastic partial differential equation 
$$du_\varepsilon (t)= \sum\limits_{|k| \leqslant 2p} a_k D_x^k u_\varepsilon dt+ \theta (x)g(u_\varepsilon,t,x)+\varepsilon dw(t)$$
is considered. The asymptotic problem setting, as the noise intensity epsi rarr 0, is investigated.
