On a dual pair of spaces of smooth and generalized random variables

A dual pairG andG* of smooth and generalized random variables, respectively, over the white noise probability space is studied.G is constructed by norms involving exponentials of the Ornstein-Uhlenbeck operator,G* is its dual. Sufficient criteria are proved for when a function onL(ℝ) is theL-transform of an element inG orG*.
