DESCRIPTION:Speakers: Dinghao Zhu (UCLouvain)\n\nWe discuss dark soliton g
 as and its connection with the generalized Riemann problem for the defocus
 ing nonlinear Schrödinger equation. The latter extends the classical prob
 lem by replacing its constant states with periodic finite-gap backgrounds.
  Starting from a continuum limit of multisoliton solutions\, we construct 
 arbitrary-genus gas potentials that approach a finite-gap wave on the left
  and a constant background on the right. For step-like initial data approa
 ching two elliptic backgrounds\, we develop direct scattering and transfor
 m the inverse problem into a full dark soliton gas Riemann–Hilbert probl
 em with a radiative component. Under suitable spectral and regularity assu
 mptions\, we analyze the long-time behavior of the resulting solutions usi
 ng the Deift–Zhou nonlinear steepest descent method. This talk is based 
 on three related works. The first is joint work with Marco Bertola\, Dengs
 han Wang\, and Peng Yan\, and the third is joint work with Dengshan Wang.\
