关于Thiele型向量值连分式收敛定理的一个注记
A Note on Convergence Theorem for Thiele-Type Vector Valued Continued Fractions
【摘要】 本文利用推广的向量连分式向后递推算法重新给出了文[3]中定理1的证明,并改进了其结果。最后,在稍强的条件下,给出了这一类收敛向量连分式的一个更精致的截断误差估计。
【Abstract】 We improve the proof and results of Theorem 1 in [3] by means of the modifiedclassical backward algorithm which is a generalization of the scalar case. We give also a morerefined truncation error bound for this class of vector continued fractions under a slightlystronger condition.
