摘要
研究了复有界线性算子空间中的非线性最佳逼近问题,给出了其内的RS-集(严格RS-集)逼近的特征及广义强唯一性定理.
This paper is concerned with the problem of the nonlinear best approximation in spaces of complex bounded linear operators and establishes the characterization and the generalized strong unicity theorem of the best approximation from an RS-set (a strict RS-set) in these spaces.
