Strong Unicity Constants in Chebyshev Approximation,hebyshev spaces. Results of this type were proved by several authors in the special case of Haar spaces and spline spaces. Strong unicity constants are used to obtain error estimations for approximations computed by Remez type algorithms.

Knot-Elimination; Reversal of the Oslo Algorithm,Given a spline function of any order, we consider the possibility of approximating it, to within an acceptable tolerance, by a spline function of the same order but with fewer knots, and of achieving this end through a finite algorithm.

Fourier Methods in Practical Approximation,On the basis of the Carathéodory-Fejér method (in conjunction with some auxiliary tools) we obtain simple but good substitutes for the Zolotarev polynomials and certain generalizations. Thereby we give rather sharp error bounds for the approximations involved. Further we point out certain relations to summability theory.
