Parabolically connected subgroups
I. V. Netai M. V. Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
All reductive spherical subgroups of the group $\operatorname{SL}(n)$ are found for which the intersections with every parabolic subgroup of $\operatorname{SL}(n)$ are connected. This condition guarantees that open equivariant embeddings of the corresponding homogeneous spaces into Moishezon spaces are algebraic.
Bibliography: 6 titles.
Keywords:
