Exchange Algorithms, Error Estimations and Strong Unicity in Convex Programming and Chebyshev Appro a finite sequence of finite sub-problems, which is called an optimization problem with respect to a .. Modifying a strategy of Carasso and Laurent we replace in the.exchange theorem the zero-checks by practical δ-checks with δ > 0. This allows us to reduce the numerical calculations of the function

Birkhoff Interpolation on the Roots of Unity,, the general problem of Birkhoff interpolation on the roots of unity has not received enough attention. Even for a three row incidence matrix E we do not know any simple criterion for settling its regularity on the cube roots of unity.

Introduction

H-Sets for Non-Linear Constrained Approximation,ar approximation by sets not satisfying the Haar condition. The usefulness of H-sets for the characterisation and anlysis of best approximation in this non-Haar setting is set out in Brannigan [1]. A complete exposition in terms of functions in a normed linear setting is given in Brannigan [2]. For
