Simulation of Gaussian random fields on surfaces using the isogeometric finite element method
Helmut Harbrecht, Florian Sonderegger, Remo von Rickenbach
We are concerned with the fast simulation of random fields on closed surfaces in which are generated by the (Whittle-) Matérn class of covariance functions. To this…

On the Compressibility of Integral Operators in Anisotropic Wavelet Coordinates
Helmut Harbrecht, Remo von Rickenbach
The present article is concerned with the s*-compressibility of classical boundary integral operators in anisotropic wavelet coordinates. Having the s*-compressibility at hand, one…
