Soundararajan %J Mathematics %D 2007 %I arXiv %X Assuming the Riemann Hypothesis we establish an upper bound for the sum of the M{\" o}bius function up to $x$. Our method is based on estimating the frequency with which intervals of a given length can contain an unusual number of ordinates of zeros of the Riemann zeta-function. %U http://arxiv.org/abs/0705.0723v2
