In this paper, we apply∂‾ steepest descent method to study the Cauchy problem for the nonlinear short-pulse equation u x t= u+ 1 6 (u 3) x x, u (x, 0)= u 0 (x)∈ H (R), where H (R)= W 3, 1 (R)∩ H 2, 2 (R) is a weighted Sobolev space. The solution of the short-pulse equation is constructed via a solution of Riemann-Hilbert problem in the new scale (y, t). In any fixed space-time cone C (y 1, y 2, v 1, v 2)={(y, t)∈ R 2: y= y 0+ v t, y 0∈[y 1, y 2], v∈[v 1, v 2]}, we compute the long time asymptotic expansion of the solution u (x, t), which implies soliton resolution conjecture consisting of three terms: the leading order term can be characterized with an N (I)-soliton whose parameters are modulated by a sum of localized soliton-soliton interactions as one moves through the cone; the second| t|− 1/2 order term coming from soliton-radiation interactions on continuous spectrum up to an residual error order O (| t|− 1) from a∂‾ equation. Our results also show that soliton solutions of the short-pulse equation are asymptotically stable.
