White noise distribution theory over the complex Gaussian space is established on the basis of the recently developed white noise operator theory. Unitarity condition for a white noise operator is discussed by means of the operator symbol and complex Gaussian integration. Concerning the overcompleteness of the exponential vectors, a coherent state representation of a white noise function is uniquely specified from the diagonal coherent state representation of the associated multiplication operator.
Keywords: white noise, coherent state representation, Fock space, quantum stochastic differential equation, unitarity condition, operator symbol
