Some categorical remarks on coarse subspaces of coarse spaces
Muneto Miyaji, Hiroaki Nagaya, Kento Ogawa +1
In this paper, we provide a categorical framework for understanding coarse subspaces of coarse spaces. First, we introduce the notion of a controlled total relation between coarse…
The intersection of two real flag manifolds in a complex flag manifold
Osamu Ikawa, Hiroshi Iriyeh, Takayuki Okuda +2
We give a necessary and sufficient condition for two real flag manifolds, which are not necessarily congruent, in a complex flag manifold to intersect transversally in terms of the…
Some remarks on real minimal nilpotent orbits and symmetric pairs
Takayuki Okuda
For a non-compact simple Lie algebra over , we denote by the unique complex nilpotent orbit in $\mathfrak{…
Zariski dense discontinuous surface groups for reductive symmetric spaces
Kazuki Kannaka, Takayuki Okuda, Koichi Tojo
Let be a homogeneous space of reductive type with non-compact . The study of deformations of discontinuous groups for was initiated by T.~Kobayashi. In this paper, w…
Proper SL(2,R)-actions on homogeneous spaces
Maciej Bochenski, Piotr Jastrzebski, Takayuki Okuda +1
We study the existence problem of proper actions of SL(2,R) on homogeneous spaces G/H of reductive type. Based on Kobayashi's properness criterion [Math. Ann. (1989)], we show that…
