我们证明了在多维短程势散射中,N体系统的散射算子的高速极限唯一地决定了势。对于给定的长程势,N体系统的短程势由修正的多拉德散射算符的高速度极限唯一确定。此外,我们还证明了任何一个Dollard散射算子唯一地决定了总势。我们还得到了一个带误差项的重建公式。我们的简单证明使用了几何时间依赖方法。
We prove that in multidimensional short‐range potential scattering the high velocity limit of the scattering operator of an N‐body system determines uniquely the potential. For a given long‐range potential the short‐range potential of the N‐body system is uniquely determined by the high velocity limit of the modified Dollard scattering operator. Moreover, we prove that any one of the Dollard scattering operators determines uniquely the total potential. We obtain as well a reconstruction formula with an error term. Our simple proof uses a geometrical time‐dependent method.
