The celebrated Riemann Hypothesis (RH) is proved based on a new absolute convergent expression of , which was obtained from the Hadamard product, through paring and , and putting all the multiple zeros together in one factor, i.e. where , and are the complex conjugate zeros of , and are real numbers, is the real (unique and unchangeable) multiplicity of , are arranged in order of increasing , i.e., , . Then, according to the functional equation , we have which, owing to the uniqueness and unchangeableness of (see Lemma 3 for the proof details), is finally equivalent to Thus, we conclude that the RH is true.
