Abstract
We consider the projective differential geometry of m-dimensional plane submanifolds of manifolds G(m,n) in projective space Pn containing a finite number of developable surfaces. To study such submanifolds we use the Grassmann mapping of manifolds G(m,n) of m-dimensional planes in projective space Pn to (m + 1)(n − m)dimensional algebraic manifold (m,n) of space PN, where N 1. This mapping combined with the method of external Cartan’s forms and moving frame method made it possible to determine the dependence of considered manifolds structure and the configuration of the (m − 1)-dimensional characteristic planes and (m + 1)dimensional tangential planes of developable surfaces that belong to considered manifolds.
