Surface finite element approximation of spherical Whittle--Matérn Gaussian random fields
Erik Jansson, Mihály Kovács, Annika Lang
Spherical Whittle--Matérn Gaussian random fields are considered as solutions to fractional elliptic stochastic partial differential equations on the sphere. Approximation is done w…
