2015/10/8
We present a new third-order central scheme for approximating solutions of systems of conservation laws in one and two space dimensions. In the spirit of Godunov-type schemes, our method is based on r...

A principal wishes to screen an agent along several dimensions simultaneously.
The agent has quasilinear preferences that are additively separable across the various
components. We consider a robust...
