This talk is about the application of semidefinite lifts to solving polynomial optimization problems. Such lifts can be used to solve non-convex polynomial optimization problems globally by reformulating them as semidefinite problems. However, the size of lifted semidefinite formulations is necessarily large in general because of an obstruction of a combinatorial nature which is expressed in terms of the facial structure of the sum-of-square cones.
