关于Toeplitz矩阵乘积迹逼近的误差界的注记
Note on Error Bound for Trace Approximation of Products of Toeplitz Matrices
摘要:
研究了在原点具有奇异性的$[-π,π]$上可积函数生成的Toeplitz矩阵乘积迹的积分极限逼近的误差阶.虽然\cite{Lieberman-Phillips-2004}的定理2导出了上述近似的一个尖锐的误差阶,但它的证明含有\cite{Ginovyan-Sahakyan-2013}指出的不准确性。本文重新研究了\cite{Lieberman-Phillips-2004}的定理2,并给出了另一种证明.
英文摘要:
We investigate error orders for integral limit approximations to traces of products of Toeplitz matrices generated by integrable functions on $[-π,π]$ having some singularities at the origin. Even though a sharp error order of the above approximation is derived in Theorem~2 of \cite{Lieberman-Phillips-2004}, its proof contains an inaccuracy as pointed out by \cite{Ginovyan-Sahakyan-2013}. In the present paper, we reinvestigate the claim given in Theorem~2 of \cite{Lieberman-Phillips-2004} and give an alternative proof of their claim.
