摘要:Inverse scattering problem of the high-order zeros scattering data is one of the hot issues in the study of discrete spectra in the inverse scattering transform method. This report will introduce the relevant progress in the study of discrete spectra in the inverse scattering transform method of integrable systems, including multiple algebraic discrete spectra, multiple geometric discrete spectra and asymptotic analysis of the non-elementary higher-order-zeros solitons. Further, we will study the multiple geometric discrete spectral problem of the Sasa-Satsuma equation via combining the inverse scattering transform method based on Riemann-Hilbert problem with the Darboux transformation induced by a rank-r (r>1) projection matrix.
