In this paper we establish commmutator estimates for the Dirichlet-to-NeumannMap associated to a divergence form elliptic operator in the upper half-space$\mathbb{R}^{n+1}_+:=\{(x,t)\in \mathbb{R}^n \times (0,\infty)\}$, withuniformly complex elliptic, $L^{\infty}$, $t$-independent coefficients. By astandard pull-back mechanism, these results extend corresponding results ofKenig, Lin and Shen for the Laplacian in a Lipschitz domain, which haveapplication to the theory of homogenization.

$L^2$ estimates for commutators of the Dirichlet-to-Neumann Map  associated to elliptic operators with complex-valued bounded measurable  coefficients on $\mathbb{R}^{n+1}_+$
