On the Growth of Lebesgue Constants for Degree One Fekete Points in terms of the Dimension (2305.01699v1)
Published 2 May 2023 in math.NA and cs.NA
Abstract: We discuss the growth of the Lebesgue constants for polynomial interpolation at Fekete points for fixed degree (one) and varying dimension, and underlying set $K\subset \Rd$ a simplex, ball or cube.
