Summary: The main result of this paper is the existence of a hyperinvariant subspace of the weighted composition operator $Tf=vf\circ\tau$ on $L^p([0,1]^d)$, ($1 \leqslant p \leqslant \infty$) when the weight $v$ is in the class of "generalized polynomials" and the composition map is a bijective ergodic transform satisfying a given discrepancy estimates. The work is based on the construction of a functional calculus initiated by Wermer and generalized by Davie.

Keywords: invariant subspace, weighted composition operator, discrepancy, functional calculus
