| Research Abstract |
We investigated Ricci solitons from the view point of hypersurface geometry.
In particular, we studied locally conformally flat hypersurfaces in space forms such that
The induced metric is a Ricci soliton and the potential vector field is a principal curvature vector of the principal curvature vector of multiplicity one. Then we showed that in the case when the ambient space is Euclidean space, such hypersurface is rotationally invariant.
