Abstract: The main purpose of this thesis is to prove a conjecture of
and Goetze, which arose from their research on central limit
theorems for
diffusions with periodic drift vector fields. Their
conjecture is proved in
a more general context using rearrangement techniques and
comparison manifolds.
