Best simultaneous L1 approximations [PDF]
Journal of Approximation Theory, 1978 AbstractThree possible definitions are proposed for best simultaneous L1 approximation to n continuous real-valued functions, and the relation between best simultaneous approximations and best L1 approximations to the arithmetic mean of the n functions is discussed.

Numerical Functional Analysis and Optimization, 1998 In this exposition, we investigate in an extended framework the problem of simultaneous best approximation. Refinement of a formula for the subdifferential of restricted radius of a p-bounded set leads us to explore some interesting results on strong uniqueness of simultaneous best approximants. In particular, we also.

Invariant Points and ๐-Simultaneous Approximation [PDF]
International Journal of Mathematics and Mathematical Sciences, 2011 We generalize and extend Brosowski-Meinardus type results on invariant points from the set of best approximation to the set of ๐-simultaneous approximation. As a consequence some results on ๐-approximation and best approximation are also deduced.

New Characterization for Nonlinear Weighted Best Simultaneous Approximation
International Journal of Mathematics and Mathematical Sciences, 2009 This paper is concerned with the problem of a wide class of weighted best simultaneous approximation in normed linear spaces, and it establishes a new characterization result for the class of approximation by virtue of the notion of simultaneous regular ...

Weighted Simultaneous Approximation of the Linear Combinations of Baskakov Operators
Complexity, 2020 In this paper, the approximation property of the linear combinations of Baskakov operators is investigated by using a Jacobi weight function. Moreover, both the positive and inverse theorems for the weighted simultaneous approximation of the linear ...

Degree of simultaneous approximation by Birkhoff splines [PDF]
Journal of Numerical Analysis and Approximation Theory, 2001 In the present note we study the degree of simultaneous approximation by certain Birkhoff spline interpolation operators. Special emphasis is on estimates in terms of higher order moduli of smoothness. This generalizes earlier results of Meir and Sharma,

On simultaneous approximation [PDF]
, 2002 In this paper first we give two different definitions for best simultaneous Lp approximation to n functions and study the relation between best simultaneous approximation and best Lp approximations to the arithmetic mean of n functions.
