Invariant hypersurfaces of endomorphisms of the projective 3-space

By De-Qi Zhang


We consider surjective endomorphisms f of degree > 1 on the projective n-space with n = 3, and f^{-1}-stable hypersurfaces V. We show that V is a hyperplane (i.e., deg(V) = 1) but with four possible exceptions; it is conjectured that deg(V) = 1 for any n > 1.Comment: 16 pages; submitted to The Proceedings of the Conference on Affine Algebraic Geometry, Osaka, March 2011, in honour of Prof M.
