Long-time asymptotics of a full arbitrary-genus dark soliton gas for the defocusing nonlinear Schrodinger equation
Dedi Yan, Xianguo Geng, Mingming Chen
We introduce a full arbitrary-genus dark soliton gas for the defocusing nonlinear Schrödinger equation with finite-density boundary conditions. Starting from a generalized meromorp…

Long-time Asymptotics of a Full Camassa-Holm Soliton Gas
Dedi Yan, Xianguo Geng, Minxin Jia
We investigate the long-time asymptotics of a full soliton gas for the Camassa--Holm equation. The analysis starts from a pure-soliton Riemann--Hilbert (RH) problem with \(2N\) pol…

Large-time asymptotics of a new KdV soliton gas
Dedi Yan, Xianguo Geng, Jiao Wei
We study the large-time asymptotic behavior of a new KdV soliton gas. We first introduce a pure-soliton Riemann--Hilbert(RH) problem with \(2N\) poles and two different types of re…
