THE POLYNOMIALS WITH LEAST DEVIATION FROM ZERO IN SOME MULTIDIMENSIONAL REGION
|
Abstract:
On the basis of paper 1] we shall give in this paper some polynomials whieh have least deviation from zero in rectangle, triangle, circle and multidimensional cube, respectively. These polynomials not only bave theoretical interest but also can be applied to the process of economization polynomial approximation for several variables.
