TITLE: Are the nontrivial zeros of the Riemann zeta simple?
QUESTION [19 upvotes]: A few years ago, I found on arXiv an article in which the authors (I think they were at least two to write it) claimed to have proven that the non trivial zeros of the Riemann zeta function were all simple using the concept of Riemann surfaces. But unfortunately, I just can't find it back. Does someone know if such a result has been published and widely accepted by the mathematical community?
Thank you in advance.
