报告人:王华侨 博士,北京应用物理与计算数学研究所
摘要: The
stochastic Landau-Lifshitz-Bloch equation is recommended as the only valid
model at temperature around the Curie temperature and is especially important
for simulation of heat-assisted magnetic recording. We study the stochastic
Landau-Lifshitz-Bloch equation in case the temperature
is raised higher
than the Curie temperature. We first show the existence of invariant measures
for the Feller semigroup in bounded interval by using the Krylov-Bogoliubov
method. Moreover, in the case of degenerated additive noise, we prove the
uniqueness of invariant measures for the corresponding transition semigroup by
using the notion of asymptotic strong Feller property.
