โœฆ Synopsis

dedicated to professor dr. dr. h. c. karl zeller on the occasion of his 75th birthday

We investigate hyperinterpolation operators based on positive weighted quadrature rules, as introduced by Ian H. Sloan. If the rules are exact of double degree then, independently of the number of their nodes, the operator norms increase at the order of the minimal projections.

A method for refining high order numerical integration schemes is described. Particular focus is on integration schemes over the unit sphere with octahedral symmetry. The method is powerful enough that new integration schemes can be found from rough intuitive guesses. New schemes up to order 59 are

A function which is homogeneous in x y z of degree n and satisfies V xx + V yy + V zz = 0 is called a spherical harmonic. In polar coordinates, the spherical harmonics take the form r n f n , where f n is a spherical surface harmonic of degree n. On a sphere, f n satisfies f n + n n + 1 f n = 0, whe

Let A be a set of non-negative integers. If every sufficiently large integer is the sum of h not necessarily distinct elements of A, then A is called an asymptotic basis of order h. An asymptotic basis A of order h is called minimal if no proper subset of A is an asymptotic basis of order h. It is p

Let G be a quadrangulation on a surface, and let f be a face bounded by a 4-cycle abcd. A face-contraction of f is to identify a and c (or b and d) to eliminate f . We say that a simple quadrangulation G on the surface is k-minimal if the length of a shortest essential cycle is k(โ‰ฅ 3), but any face-
