Abstract:

In this talk, we consider the asymptotic properties for the maximum likelihood estimator of the drift estimation in a stochastic heat equation driven by additive noise. Cramér-type moderate deviations for the maximum likelihood estimator are established in three asymptotic regimes: large time asymptotics, increasing number of Fourier modes, large time asymptotics and increasing number of Fourier modes. Our methods consist of change of measure, multiple Wiener-Ito integrals and asymptotic analysis technique.
