Abstract: The question of the nonnegativity of quadratic forms on intersections of quadratic cones is considered. An answer is given in terms of Lagrange multipliers of the quadratic forms under consideration.
Keywords: quadratic form, quadratic cone, quadratic map, regular zero of a quadratic function, abnormal point, bilinear map, Sard's theorem.
