This is an expository paper which yields some results on the characteristic functions of distributions defined on Wiener space. The main one of these results is a very simple theorem (Potthoff-Streit’s theorem) which defines completely the characteristic functions of Kubo- Yokoi’s distributions. The paper deals with Hida distribution, Fock space, Wick product, test functions, exponential test functions, trace operator, Stratonovich multiple integrals, Wiener product. Also one considers the problem of defining positive measures on Wiener spaces.
