We also bound theorder of the relaxation at which flat truncation holds. As corollaries, we conclude that flat truncation holds:$\bullet$ when regularity conditions, known as Boundary Hessian Conditions, hold: this resultimplies that flat truncation and MoM exactness holds generically;$\bullet$ when the support of the quadratic module Q is zero-dimensional;$\bullet$ in singular cases, flat truncation holds for the MoM relaxation extended with the polarconstraints when the real variety of polar points is finite. Effective numerical computations illustrate these flat truncation properties.
