摘要:

通过构造一种新的耦合,建立了一类带乘性噪声的时滞随机微分方程泛函解的log-Harnack不等式.作为应用,给出了强Feller性质和热核估计w.r.t.准不变概率测度的解的相关转移半群导出。研究了无量纲的\cite{W97}意义下的Harnack不等式.

英文摘要:

By constructing a new coupling, the log-Harnack inequality is established for the functional solution of a delay stochastic differential equation with multiplicative noise. As applications, the strong Feller property and heat kernel estimates w.r.t. quasi-invariant probability measures are derived for the associated transition semigroup of the solution. The dimension-free Harnack inequality in the sense of \cite{W97} is also investigated.
