Codimension reduction for real submanifolds of quaternionic projective space

Jung-Hwan Kwon and Jin Suk Pak

Abstract

In this paper we prove a reduction theorem of the codimension for real submanifold of quaternionic projective space as a quaternionic analogue corresponding to those in Cecil [4], Erbacher [5] and Okumura [9], and apply the theorem to quaternionic $CR$-submanifold of quaternionic projective space.

Keywords: quaternionic projective space, reduction theorem, qua-ternionically invariant subspace, quaternionic $CR$-submanifold, lift flat
