Title: 
Finite morphisms between projective hypersurfaces

Abstract: 
It is expected that the finite morphisms between smooth
projective hypersurfaces in CP^n are very rare. We show that there 
are no nontrivial finite morphisms f : X \rightarrow Y between Fano 
hypersurfaces X and Y if deg(X) < 2 deg(Y) and dimX = dimY > 2.
