dc.descriptionWe propose an extension of a result by Repetowicz et al. about Wick's theorem and its applications: we first show that Wick's theorem can be extended to the uniform distribution on the sphere and then to the whole class of elliptical distributions. Then, as a special case, we detail this result for distributions that are Gaussian scale mixtures. Finally, we show that these results allow to recover easily a theorem by Folland about integration of polynomials over the sphere.
