Wick Polynomials

Part of the Lecture Notes in Mathematics book series (LNM, volume 849)


We introduce the notion of Wick polynomials which are natural multi-variate versions of Hermite polynomials. We present their most important properties, and with their help we give a decomposition of the Hilbert space of square integrable random variables measurable with respect to a stationary Gaussian random field to the direct sum of orthogonal, shift invariant subspaces.
