Orbit structures on real double flag varieties for the Siegel parabolic subgroups

Kyo Nishiyama, Taito Tauchi

Let $G$ be a connected reductive algebraic group over $R$ , and $H$ its symmetric subgroup. For parabolic subgroups $P_{G} \subset G$ and $P_{H} \subset H$ , the p…

Real double flag variety for the symmetric pair $(U (p, p), G L_{p} (C))$ and Galois cohomology

Kyo Nishiyama, Taito Tauchi

Let $G$ be the indefinite unitary group $U (p, p)$ , $H ≃ G L_{p} (C)$ its symmetric subgroup, $P_{S}$ the Siegel parabolic subgroup of $G$ , and $B_{H}$ a Borel subgroup of…
