Query: Harnack Inequality for Functional SDEs with Bounded Memory   We use a coupling method for functional stochastic differential equations
with bounded memory to establish an analogue of Wang's dimension-free Harnack
inequality \cite{MR1481127}. The strong Feller property for the corresponding
segment process is also obtained.
