Abstract: The homotopy class of a self map of a complex projective space is well known to be classified by a degree detected in two dimensional cohomology. An analogous result is proved for the rationalization of the Grassmann manifold of complex $ n$-planes in complex $ N$-space, provided $ N \ne 2n$ and the degree is not zero.
