A new cubature formula with weight functions on the disc, with error estimates
O. Kounchev, H. Render
We introduce a new type of cubature formula for the evaluation of an integral over the disk with respect to a weight function. The method is based on an analysis of the Fourier ser…

Discrete Hybrid Polyharmonic Cubature Formulas with weight on the disc. with error bounds
O. Kounchev, H. Render
This paper is a second part of our study of the Discrete Polyharmonic Cubature Formulas on the disc. It completes our study and provides a satisfactory cubature formula in terms of…
