Extreme Points of the Unit Ball B4 in the Space of Real Polynomials of Degree at most Four with the Supremum Norm
Jan-Michael Holzinger, Róbert Vajda · 2022
Denote by Pnthe space of real polynomials p of degree at most n equipped with the sup norm on the interval I = [−1, 1]. The unit ball Bnwith respect to the sup norm is a compact convex set. Let EBndenote the set of the extreme points of Bn.
