| Research Abstract |
We study non-symmetric spherical homogeneous spaces of complex semisimple Lie groups by strongly visible actions. We treat spherical and 4-symmetric space and a certain Cayley-type spherical variety which are irreducible affine homogeneous spaces and spherical complex nilpotent orbits in a complex semisimple Lie algebra which are quasi-affine. Further, we give a concrete description of a slice which meets every orbit.
