Optimal Quadrature of Convex Functions,At the instigation of H. Brass we consider the following question: Let us assume that for given fixed nodes a=x.<x. ...<x. =b the values f(x.)=:f. , i = 1,...,n, of a convex function f:→ IR are known. How can we compute the endpoints I, S (I<S) of the interval

Gaussian Cubature Formulae of Degree 2 and 3,For integrals with convex domains of integration we consider cubature formulae of degree r, r∈{2, 3}, with only positive weights and all nodes inside the domain. We show, that the minimal number of nodes for such formulae varies from 3 to at least 5 (for r=2) and from 3 to at least 9 (for r=3) in dependence of the shape of the domain.
