令 9C 为希尔伯特空间 L2(Rn)(n >_ 3),并令 {H(t) = Ho + V(t), t R1} 为 9C 中具有与时间相关的扰动 V(t) 的薛定谔算子族,其中 Ha=-d 是 Rn 中的负拉普拉斯算子。我们假设 {-iH(t) ;; t R1} 生成酉演化群 {U(t, s) ; -oo < t, s < oo},这种情况下散射理论的基本问题如下。 (1)强极限什么时候做
Let 9C be the Hilbert space L2(Rn)(n >_ 3) and let {H(t) = Ho + V(t), t R1} be a family of Schrodinger operators in 9C with a time-dependent perturbation V(t), where Ha=-d is the negative Laplacian in Rn. We suppose that {-iH(t) ;; t R1} generates a unitary evolution group {U(t, s) ; -oo < t, s < oo}, Fundamental problems in scattering theory under these circumstances are as follows.
