Approximating Gaussian Whittle-Matern Fields over Well-Centered Triangulations of Riemannian Manifolds
arXiv:2606.13827v2 Announce Type: replace-cross Abstract: Markovian Whittle-Mat\'ern fields have been convergently approximated by discrete Gauss Markov Random Fields (GMRFs) with sparse precision matrices using a Finite Element approximation of the two-parameter family, \[ (\kappa^2 - \Delta)^{\alp
