A Converse Sum of Squares Lyapunov Result With a Degree Bound [PDF]
IEEE Transactions on Automatic Control, 2012 Sum of Squares programming has been used extensively over the past decade for the stability analysis of nonlinear systems but several questions remain unanswered. In this paper, we show that exponential stability of a polynomial vector field on a bounded set implies the existence of a Lyapunov function which is a sum-of-squares of polynomials.

Azimuthal distinguishability of entangled photons generated in spontaneous parametric down-conversion [PDF]
, 2007 We experimentally demonstrate that paired photons generated in different sections of a down-conversion cone, when some of the interacting waves show Poynting vector walk-off, carry different spatial correlations, and therefore a different degree of ...
