Abstract

Wick tensors are used to describe homogeneous chaos and to define multiple Wiener integrals. The Wiener-Itô decomposition is expressed by the formula φ(x) = ∑n=0∞1/n!∫B [Dn (μφ)(0)]∼(x+iy,....,x+iy)dμ(y). We use this formula to interpret Hida's original idea of generalized multiple Wiener integrals as generalized functions acting on the space of test functions.
