Add to ORKG3 pages, 2 figures. For the proceedings of MENU 2001, Washington D.C., July 26-31, 2001The scalar-isoscalar, scalar-isotensor and vector-isovector pion-pion partial wave amplitudes are analyzed. Preliminary results indicate that only the scalar-isoscalar amplitude fitted to the "down-flat" data satisfies Roy's equations and consequently crossing symmetry
