Let f : M → R 2 be a smooth map of a closed n-dimensional manifold (n 2) into the plane and let π n+2 2 : R n+2 → R 2 be an orthogonal projection. We say that f has the standard lifting property, if every embedding f : M → R n+2 with π n+2 2 • f = f is standard in a certain sense. In this paper we g
