摘要
Let Gi be closed Lie groups of U(n), omega(i) be bounded G(i)-invariant domains in DOUBLE-STRUCK CAPITAL C-n which contains 0, and O(DOUBLE-STRUCK CAPITAL C-n)(Gi) = DOUBLE-STRUCK CAPITAL C, for i = 1, 2. It is known that if f: omega(1) ->} omega(2) is a proper holomorphic mapping, and f(-1){0} = {0}, then f is a polynomial mapping. In this paper, we provide an upper bound for the degree of such a polynomial mapping using the multiplicity of f.
