翻译后摘要:我们研究空间切断P(P)2哈密顿。我们证明了阈值外纯点谱的局部有限性,极限吸收原理和这种哈密顿量的散射的渐近完备性。我们的结果意味着奇异连续谱的存在。
Abstract:We study spatially cut-off P(ϕ)2 Hamiltonians. We show the local finiteness of the pure point spectrum outside of thresholds, the limiting absorption principle and asymptotic completeness of scattering for such Hamiltonians. Our results imply the absence of singular continuous spectrum.
