Abstract

A stochastic “Fubini” lemma and an approximation theorem forintegrals on the plane are used to produce a simulation algorithmfor an anisotropic fractional Brownian sheet. The convergence rateis given. These results are valuable for any value of the Hurstparameters $(\alpha_1,\alpha_2)\in ]0,1[^2,\alpha_i\neq\frac{1}{2}.$ Finally, theapproximation processis iterative on the quarter plane $\mathbb {R}_+^2.$ A sample of such simulations can be used to test estimatorsof the parameters αi,i = 1,2.
