摘要

本文研究了斜H-Toeplitz算子的复对称性。探讨了倾斜H-Toeplitz算子（即倾斜Toeplitz算子和倾斜Hankel算子）相对于加权复合算子的限制复对称的必要条件，并给出了不足条件的反例。得到了斜H-Toeplitz谱半径的上界。

Complex Symmetry of Slant H-Toeplitz Operators

In this paper complex symmetry of slant H-Toeplitz operator is studied. Necessary conditions for complex symmetry of restrictions of slant H-Toeplitz operator, namely slant Toeplitz operator and the slant Hankel operator, with respect to a weighted composition operator are explored along with counterexamples for insufficient conditions. The upper bound for the spectral radius of the slant H-Toeplitz is also obtained.
