竹内 有哉 氏 (筑波大学)
Kohn-Rossi cohomology of spherical CR manifolds (Japanese)
[ 講演概要 ]
The Kohn-Rossi cohomology is a CR analog of the Dolbeault cohomology and is one of fundamental invariants in CR geometry. In this talk, we prove some vanishing theorems for the Kohn-Rossi cohomology of some spherical CR manifolds. To this end, we use a canonical contact form defined via the Patterson-Sullivan measure and Weitzenböck-type formulae.
