- Title: Automorphism groups of
certain unbounded domains - Speaker: Dr. Yoshikazu Nagata(GAIA) - Abstract: I will explain
first the Calabi-Markus phenomenon, that is, for certain pseudo-Riemannian
symmetric spaces, any discrete group which acts properly discontinuously is
finite.
Second, for some
unbounded homogeneous domains in the complex euclidean spaces, I will show that
there are no co-compact discrete subgroups in the holomorphic automorphism
groups.
This
result is related to the Calabi-Markus phenomenon. - Place: GAIA Seminar Room (# 106, Math Science bldg.) |
