摘要
讨论了sl2(C)中矩阵乘积的迹的性质;证明了离散Schrodinger算子H在其势Vn为Thue-Morse序列或准对称序列时,在空间Co(Z)内不存在特征向量.
The properties of the trace of mains product in sl2(C) are studied. We provethat the discrete Schrodinger H with potential taking the form of Thue-Morse sequence orquasi-symmetry sequence has no eigenvectors in the space CO(Z).
