Abstract:In this talk, we state the asymptotic properties for the maximum likelihood estimator (MLE) of the drift estimation in a stochastic fractional heat equation driven by additive noise. Via the change of measure method and asymptotic analysis technique, we establish the exponential nonuniform Berry-Esseenbound and (selfnormalized)Cramér-type moderate deviation for the MLE in three asymptotic regimes: large time asymptotics, increasing number of Fourier modes, large time asymptoticsand increasing number of Fourier modes.
