Universal quadrature rules in the space of periodic functions, mostly we are interested in rules, which work well for many classes of functions. It is the aim of this paper to make this idea more precise by the definition and discussion of “universal (quadrature) rules”.

Gaussian Quadrature Formulae Involving Derivatives of Lacunary Type,e pairs by an incidence matrix .where .. = 1 if (.) ∈ ., and .. = 0 otherwise. If the knots .. and the weights .. are chosen so that the formula will be exact for polynomials of utmost degree, we call the formula to be of ..

Jacobi Moments and a Family of Special Orthogonal Polynomials,s .since the recurrence relation for the .may be derived via modified moments (e.g. Chebyshev moments) using a Cholesky type process. Moreover, Gauß-type formulas can be constructed numerically from the recurrence relation.

Asymptotic Behaviour of Peanokernels of Fixed Order,ting of all functions with an . − 1th absolutely continuous derivative. If .. is exact for polynomials of degree . − 1, the error can be estimated for every . ∈ .. [−1, 1] by using the . th Peano kernel: . (cf. Braß , p.39). We therefore have the unimprovable bounds . and
