THE BEST APPROXIMATING OF BOUNDED LINEAR OPERATOR IN THE SPACE W AND APPLICATION
W空间中有界线性算子的最佳逼近及其应用

In this paper, we give the best approximating A. for { (xi, yi) c, d] of following form of bounded linear operator A in the space W, and discussed convergences of An. We also give the numerical solution of linear operator equation (An) (x, y) = f(x, y) for application.
