Shcherbakov N.R. On a special class of planar surfaces in multidimensional projective space. Tomsk State Pedagogical University Bulletin. 2000. Issue 2 (18). P. 49-51

Abstract: A family of planes generalizing tangentially degenerated surfaces in the n-dimensional projective space is studied. By use of a class of planes from the family, manifolds of singular points are.
