By applying a Fourier analytic argument, we prove that, for every α∈(0,2), the N-parameter harmonizable fractional α-stable field (HFαSF) is locally nondeterministic. When 0<α<1, this solves an open problem in Nolan (1989). Also, it allows us to establish the joint continuity of the local times of an (N,d)-HFαSF for an arbitrary α∈(0,2), and to obtain new results concerning its sample paths.
