Abstract
We consider the Gaussian free field on $Z^d$, $d\geq3$, and prove that the critical density for percolation of its level sets behaves like $1/d^{1+o(1)}$ as $d$ tends to infinity. Our proof gives the principal asymptotic behavior of the corresponding critical level $h_*(d)$. Moreover, it shows that a related parameter $h_{**}(d)$ introduced by Rodriguez and Sznitman in [23] is in fact asymptotically equivalent to $h_*(d)$.
