For any irrational x # [0, 1] we denote by p n (x)Âq n (x), n=1, 2, ... the sequence of its continued fraction convergents and define % n (x) :=q n |q n x&p n |. Also let T: [0, 1] Ä [0, 1] be defined by T(0)=0 and T(x)=1Âx&[1Âx] if x{0. For some random variables X 1 , X 2 , ..., which are connected

Let N$ be the dual of a nuclear Fre chet space N and % a Young function on [0, + [. We define the space F % (N$) of holomorphic functions on N$ which satisfy: for all m>0 and p # N there exists K 0 such that
Let %* be the conjugate function of % and G %* (N ) the space of holomorphic functions on N which satisfy: there exists p # N, m>0 and M 0 such that | g(u)| Me %*(m |u| p ) .
We prove that the Laplace transform realizes a topological isomorphism of the strong dual of F % (N$) on G %* (N ). An application of this result to white noise analysis is given.
