Abstract
A numerical analysis to the scalar form factor in the pi pi and KK coupled- channel system is made by solving the coupled-channel dispersive integral e quations by the iteration method. The solutions are found not to be unique. Physical application to the pi pi central production in the pp --> pp pi p i process is discussed based upon the numerical solutions we found.
