What is widely considered in engineering circles as an elegant but otherwise useless mathematical strategy from the nineteenth century gets a makeover from a professor and graduate student pair from ...

We develop a family of fast methods for approximating the solutions to a wide class of static Hamilton-Jacobi PDEs; these fast methods include both semi-Lagrangian and fully Eulerian versions.

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...
