Their topics include the degree of uniform approximation
by generalized discrete singular operators, Voronovskaya-like asymptotic expansion for generalized discrete singular operators, global smoothness preservation and simultaneous approximation by generalized discrete singular operators, the degree of Lp approximation for multivariate generalized discrete singular operators, and the degree of approximation by multivariate complex generalized discrete singular operators.
On uniform approximation
by Bleimann, Butzer and Hahn on all positive semiaxis.
The Carleman's theorem is a pointwise approximation result which generalizes the Weierstrass result on uniform approximation
by polynomials in compact intervals, since on any compact subinterval of R, the entire function can in turn be approximated uniformly by polynomials, more exactly by the partial sums of is power series (see Remark 2.
In , the optimal piecewise uniform quantizer for that source geometry has been designed assuming four cases for the piecewise uniform approximation
of the input radius PDF.
Similar to , we consider an alternative approach based on the use of polynomials of best uniform approximation
to the function 1/[lambda].
COMPUTATIONAL TECHNIQUES: PIECEWISE UNIFORM APPROXIMATION
It is probably impossible to generate a uniform approximation
within the limits of a linear model in the whole interval [0; 40] because periodic functions [f.
