"The coupled processes \u2013 the \u03C0\u03C0 scattering, \u03C0\u03C0 KK, \u03C0\u03C0 \u03B7\u03B7 and J=\u03C8 \u03D5 \u03C0\u03C0;\u03D5KK \u2013 are considered in the 2- and 3-channel approaches for studying f0-mesons. An applied modelindependent method of analysis is based on analyticity and unitarity and uses an uniformization procedure. It is shown that for obtaining correct values of the f0-meson parameters a one-channel dispersive equation (Roy\u2019s equations) analysis of the \u03C0\u03C0 scattering is not enough, even for the f0(600) which is in the elastic region of the \u03C0\u03C0 scattering below the thresholds of coupled channels. At least, the combined 3-channel analysis of data on coupled processes \u03C0\u03C0 \u03C0\u03C0;KK;\u03B7\u03B7 is needed, which is carried out adding the data on decays J=\u03C8 \u03D5 \u03C0\u03C0;\u03D5KK from Mark III , DM2 and BES Collaborations. The latter allows us considerably to diminish possible scenarios of the resonance representations on the Riemann surface of the S-matrix, which give the similar description of the multi-channel \u03C0\u03C0 scattering and, however, the quite different parameters of some resonances. There are changed most considerably parameters of the f0(600) \u2013 now the obtained mass is in some accordance with prediction by S. Weinberg on the basis of mended symmetry.
