Abstracts
We consider spaces of test and regular generalized functions of white noise. These spaces 20 years ago were characterized by holomorphy on infinite dimensional spaces together with an integrability condition. We, instead, give a characterization in terms of U-functionals, i.e., classic holomorphic functions on the one dimensional field of complex numbers, together with the same integrability condition. The characterization of regular generalized functions is useful for solving singular SPDEs. Whereas, the characterization of test functions is useful for showing smoothness of solutions to SPDEs in the sense of Malliavin calculus. We present concrete examples confirming the usefulness in both cases.
