Gauss-Kronrod quadrature formulas
We prove new upper and lower bounds for high order Peano error constants of Gauss-Kronrod quadrature formulas. The bounds are of sharp order. They are useful for comparisons with Clenshaw-Curtis and related formulas. The bounds are based on new results on the error of Gauss-Kronrod quadrature of Chebyshev polynomials.
