Conditions of Extremality of an Admissible Element for the Problem of Best Simultaneous Approximation in the Sense of the Squared Norm Of Several Elements of a Linear Normed Space by a Subset of this Space
An important class in approximation theory is formed by problems of best simultaneous approximation of several elements of a linear normed space by a subset of this space. The problem of best simultaneous approximation of several elements of a linear normed space by a subset of this space consists i...
