Harmonic
Maps to the Weil-Petersson Completion of Teichmueller Space
The talk
will review the structure of the metric completion of Teichmueller space with
respect to the Weil-Petersson metric as a nonpositively curved Alexandrov space.
Harmonic maps with Teichmueller space as a
target may be used to study representations of fundamental groups into mapping
class groups. A regularity result for the case of two dimensional domains will
be discussed.
