Sum-of-squares hierarchy lower bounds for symmetric formulations
, 2016 We introduce a method for proving Sum-of-Squares (SoS)/ Lasserre hierarchy lower bounds when the initial problem formulation exhibits a high degree of symmetry.

A Heuristic Method for Certifying Isolated Zeros of Polynomial Systems
Mathematics, 2018 In this paper, by transforming the given over-determined system into a square system, we prove a necessary and sufficient condition to certify the simple real zeros of the over-determined system by certifying the simple real zeros of the square system ...

On sums of three squares [PDF]
Journal de théorie des nombres de Bordeaux, 2003 We address the question of when an integer in a totally real number field can be written as the sum of three squared integers from the field and more generally whether it can be represented by a positive definite integral ternary quadratic form over the field.

A Nearly Tight Sum-of-Squares Lower Bound for the Planted Clique Problem
, 2016 We prove that with high probability over the choice of a random graph $G$ from the Erd\H{o}s-R\'enyi distribution $G(n,1/2)$, the $n^{O(d)}$-time degree $d$ Sum-of-Squares semidefinite programming relaxation for the clique problem will give a value of at
