We consider the Buhmann class of radially symmetric and compactly supported covariance functions, that includes the most prominent classes used in both numerical analysis and spatial statistics literature. We discuss a very simple difference operator and report the conditions for which the application of it to Buhmann functions preserves positive definiteness on m-dimensional Euclidean spaces. We also show a relation between the Zastavnyi-Porcu problem [39] for Buhmann functions and a class of completely monotone functions.
