In this chapter, we give Lie's construction of the space of spheres and define the important notions of oriented contact and parabolic pencils of spheres. This leads ultimately to a …

Problems in submanifold theory have been studied since the invention of calculus and it was started with differential geometry of plane curves. Owing to his studies of how to draw …
We prove, in a purely geometric way, that there are no connected irreducible proper subgroups of SO (N, 1). Moreover, a weakly irreducible subgroup of SO (N, 1) must either act …

A submanifold of a pseudo-Riemannian manifold is said to have parallel mean curvature vector if the mean curvature vector field H is parallel as a section of the normal bundle …
Several classes of irreducible orthogonal representations of compact Lie groups that are of importance in Differential Geometry have the property that the second osculating spaces of …
We introduce a new integral invariant for isometric actions of compact Lie groups, the copolarity. Roughly speaking, it measures how far from being polar the action is. We …

In this paper we prove that a submanifold with parallel mean curvature of a space of constant curvature, whose second fundamental form has the same algebraic type as the one …
