It is known as the Reeb theorem that if a closed differentiable manifold admits a smooth function with only minima and maxima as its critical points, then the manifold is necessarily homeomorphic to the sphere. In this talk some generalizations of this theorem will be presented for smooth maps into higher dimensional Euclidean spaces. Unlike the function case, the existence of such maps strongly affects the differentiable structure of the manifold, especially in dimension four.
