optimum operator

In this paper, using the interval maximum operator and the optimal Krawczyk operator, an interval method is proposed for linear complementarity problems with H-matrix having positive diagonal numerical results are given.

本文从Krawczyk算子及区间max运算入手,利用解非线性方程组的最佳Krawczyk算子方法,提出了解线性互补问题的一类最佳Krawczyk算子算法,给出了具体算法实例。

Meanwhile we give the necessary and su?cient condition for existence of best approx- imation operator on the linear manifold in arbitary Banach space, and obtain a representive of the corresponding best approximation operator by the normalized duality mapping.

还给出了一般 Banach 空间中线性流形上的最佳逼近算子存在的充要条件,并借助于正 规对偶映射得到了相应的最佳逼近算子的表达式。

In Orlicz spaces with Orlicz norm, a sufficient condition for the monotone property of best approximation operator is given.
