Center node: "spherical discrepancy minimization and algorithmic lower bounds for covering the sphere"
  Abstract: Inspired by the boolean discrepancy problem, we study the following optimization problem which we term \textsc{Spherical Discrepancy}: given $m$ unit vectors $v_1, \dots, v_m$, find another unit vector $x$ that minimizes $\max_i \langle x, v_i\rangle$. We show that \textsc{Spherical Discrepancy} is APX-hard and develop a multiplicative weights-based algorithm that achieves nearly optimal worst-case error bounds. We use our algorithm to give the first non-trivial lower bounds for the problem of covering a hypersphere by hyperspherical caps of uniform volume at least $2^{-o(\sqrt{n})}$, and to give a lower bound for covering a Gaussian random variable by equal-sized halfspaces. Up to a log factor, our lower bounds match known upper bounds in this regime. Finally, we show how to modify our algorithm to solve a natural version of the Koml{o}s problem for the spherical setting.
