摘要:
Let B be a simply-connected projective Variety such that the first cohomology groups of all line bundles on B are zero. Let E be a vector bundle over B and X = P(E). It is easily seen that a power of any ondomol-phism of X takes fibers to fibers. We prove that if X admits an endortiorphistri which is of degree greater than one on the, tlren E splits into a direct sum of line bundles.
