Stochastic fractional Anderson models with fractional noises

The authors are concerned with a class of one-dimensional stochastic Anderson models with double-parameter fractional noises, whose differential operators are fractional. A unique solution for the model in some appropriate Hilbert space is constructed. Moreover, the Lyapunov exponent of the solution is estimated, and its Holder continuity is studied. On the other hand, the absolute continuity of the solution is also discussed.
