AbstractThe open mapping theorem， the maximum modulus theorem and the uniqueness theorem are generalized from analytic functions to complex valued functions with C1 condition. Furthermore， the same results in highdimensional space are established， the applications of the multiplicity of root， index and degree are discussed.
Key wordsopen mapping theorem； maximum modulus theorem； uniqueness theorem
