On direct theorems for best polynomial approximation
Alaa Adnan Auad, R S AbdulJabbar · Journal of Physics Conference Series · 2018
This paper is to obtain similarity for the best approximation degree of functions, which are unbounded in L p,α ( A = [0,1]), which called weighted space by algebraic polynomials. and the best approximation degree in the same space on the interval [0,2 π ] by trigonometric polynomials of direct wellknown theorems in forms the average modules.
