The BMO-Dirichlet problem for elliptic systems in the upper-half space and quantitative characterizations of VMO

José María Martell, Dorina Mitrea, Irina Mitrea +1

We prove that for any homogeneous, second order, constant complex coefficient elliptic system $L$, the Dirichlet problem in ${\mathbb{R}}_{+}^n$ with boundary data in BMO is well-p…
