  In this paper the long-time dynamics of the massive Thirring model is
investigated. Firstly the nonlinear steepest descent method for Riemann-Hilbert
problem is explored to obtain the soliton resolution of the solutions to the
massive Thirring model whose initial data belong to some weighted-Sobolev
spaces. Secondly, the asymptotic stability of multi-solitons follow as a
corollary. The main difficulty in studying the massive Thirring model through
inverse scattering is that the corresponding Lax pair has singularities at the
origin and infinity. We overcome this difficulty by making use of two
transforms that separate the singularities.
