N2 - In this work we extend the robust version of the Sylvester-Gallai theorem, obtained by Barak, Dvir, Wigderson and Yehudayoff, and by Dvir, Saraf and Wigderson, to the case of quadratic polynomials. Specifically, we prove that if Q ? C[x1...., xn] is a finite set, |Q| = m, of irreducible quadratic polynomials that satisfy the following condition There is d > 0 such that for every Q ? Q there are at least dm polynomials P ? Q such that whenever Q and P vanish then so does a third polynomial in Q \ (Q, P). then dim(span(Q)) = Poly(1/d). The work of Barak et al. and Dvir et al. studied the case of linear polynomials and proved an upper bound of O(1/d) on the dimension (in the first work an upper bound of O(1/d2) was given, which was improved to O(1/d) in the second work).
