In this article, we consider the stochastic heat equation , with random coefficients and , driven by a sequence () of i.i.d. fractional Brownian motions of index . Using the Malliavin calculus techniques and a -th moment maximal inequality for the infinite sum of Skorohod integrals with respect to (), we prove that the equation has a unique solution (in a Banach space of summability exponent ≥ 2), and this solution is Hölder continuous in both time and space.
