A recent paper by John Urschel just came across my desk. Urschel has three papers in MathSciNet. The latest is “A cascadic multigrid algorithm for computing the Fiedler vector of graph Laplacians” in the Journal of Computational Mathematics. Like many of the authors in the Mathematical Reviews database, Urschel is not an academic mathematician. However, he does have a rather different sort of day job (well, sometimes he works Monday nights).
Note: My fellow AMS blogger, Evelyn Lamb, posted about this story a few months ago.
