Abstract
In this paper, we show an approximation in law of the fractional Brownian sheet by random walks. As an application, we consider a quasilinear stochastic heat equation with Dirichlet boundary conditions driven by an additive fractional noise.

Summary
We show an approximation in law of the fractional Brownian sheet by random walks. Β ∈ (0, 1), a fractional Brownian sheet on R is a two-parameter centered Gaussian process As an application of Theorem 1.1, in Section 3 we consider the approximation solution of a one-dimensional quasi-linear stochastic heat equation driven by fractional noise.
