Hypersurfaces in a conformally flat space with curvature collineation

International Journal of Mathematics and Mathematical Sciences, 1991
We classify the shape operators of Einstein and pseudo Einstein hypersurfaces in a conformally flat space with a symmetry called curvature collineation. We solve the fundamental problem of finding all possible forms of non-diagonalizable shape operators.

Special Recurrent Transformation in an NPR-Finsler Space

Cubo, 2012
In this paper, an infinitesimal transformation , where the vector vi is recurrent has been considered in an NPR- Finsler space. Such transformation is being called special recurrent transformation if the recurrence vector of the NPR- Finsler space is Lie
