证明了具有一般相互作用势的Fermi-Pasta-Ulam模型中渐近两孤子态的存在性。也就是说，我们展示的解决方案，其差异在λ 2从两个孤立波的线性叠加去为零，随着时间的推移到无穷大。
We prove the existence of asymptotic two-soliton states in the Fermi-Pasta-Ulam model with general interaction potential. That is, we exhibit solutions whose difference in ℓ2 from the linear superposition of two solitary waves goes to zero as time goes to infinity.
