White noise approach to stochastic integration. (English) Zbl 1119.60038

By introducing the notion of white noise adaptedness and proving the white noise analogue of the scalar type integrator inequalities introduced by L. Accardi, F. Fagnola and J. Quaegebeur [J. Funct. Anal. 104, No. 1, 149–197 (1992; Zbl 0759.60068)] which, in their terms, generalize the Hudson-Parthasarathy basic estimates of stochastic integrals, the authors show that some Hida distributions are in fact elements of the Fock space. The obtained inequalities are used to prove an analogue regularity result for solutions of white noise equations with bounded coefficients.
