Matrix Boussinesq solitons and their tropical limit (1805.09711v2)
Published 24 May 2018 in nlin.SI, math-ph, math.MP, and nlin.PS
Abstract: We study soliton solutions of matrix "good" Boussinesq equations, generated via a binary Darboux transformation. Essential features of these solutions are revealed via their "tropical limit", as exploited in previous work about the KP equation. This limit associates a point particle interaction picture with a soliton (wave) solution.
