We derive a set of new consistency conditions for the pion-pion scattering amplitude. These conditions hold for any s, t, u in the cube, 0 5 s, t, u 2 P2, with the four external mass variables off -mass -shell and restricted such that 4:. = 0, qt = s, 432 = t, and c$ = u. Using these consistency conditions, we determine the coefficients of the power series expansion of the pion-pion amplitude u...
