On the asymptotics of polynomial interpolation to \(|x|^{\alpha}\) at the Chebyshev nodes
The author studies several relations to approximate \(|x|^{\alpha}\) using Lagrange interpolation-polynomials on the Chebyshev nodes. He gives an important result about this and, also, he studies a strong asymptotics for the error formula.
