Ex-NFL Player and MIT Mathematician Urschel Solves Long-Standing Gaussian Elimination Conjecture

John Urschel, a former NFL player and MIT mathematician, posted a paper on arXiv proving that the growth factor of Gaussian elimination with partial pivoting is about n^(1/2) with high probability, resolving a long-standing conjecture by Nick Trefethen.
