A construction of curvature-adapted hypersurfaces in the product of symmetric spaces

Naoyuki Koike

In this paper, we give a construction of curvature-adapted hypersurfaces in the product $G_{1} / K_{1} \times G_{2} / K_{2}$ of (Riemannian) symmetric spaces $G_{i} / K_{i}$ ( $i = 1, 2$ ). By this constr…

Mean curvature flow for principal orbits of Hermann actions on rank two symmetric spaces

Naoyuki Koike, Sakura Nakaoka

In this paper, we illustrate the behaviour of the mean curvature flows starting from principal orbits of any commuting Hermann action of cohomogeneity two on irreducible rank two R…
