Bi-slant submanifolds of para Hermitian manifolds
(MDPI, 2019-07-11)In this paper, we introduce the notion of bi-slant submanifolds of a para Hermitian manifold. They naturally englobe CR, semi-slant, and hemi-slant submanifolds. We study their first properties and present a whole gallery of examples.
