Multisoliton solution
= Multisoliton solution
An exact nonlinear-wave solution containing several localized <solitons>. In an integrable scattering solution, these objects approach separated incoming and outgoing profiles, with collision effects encoded by position shifts and internal phases. <Bäcklund transformations> and <Hirota's bilinear method> construct examples such as the <Sine-Gordon multisoliton tau representation>.
