摘要
我们证明,在半直线上具有一般自伴边界条件的矩阵薛定谔方程,其波算子在空间中有界,其中矩阵势为缓慢衰减的自伴矩阵势,满足此外,假设且散射矩阵在零能量与无穷能量处为单位矩阵,我们证明波算子在与中有界。我们还证明,直线上矩阵薛定谔方程的波算子在空间中有界,假设扰动由原点处的点相互作用与势组成,且满足进一步,假设且散射矩阵在零能量与无穷能量处为单位矩阵,我们证明波算子在与中有界。我们由半直线上矩阵薛定谔方程的结果导出直线上矩阵薛定谔方程的结果。

备注
The paper has been edited. Details of some proofs have been added, and the results in the boundedness of the wave operators in $L^1$ and in $L^\infty.$ are stated under slightly stronger conditions in the decay at infinity of the potential
