On the Large $Λ$ Asymptotics of the One Phase Bernoulli Free Boundary Problem

RESUMO

In this paper, we investigate the asymptotic behavior of minimizers $u_\Lambda$ of the Bernoulli functional $\int_D |\nabla v|^2 \, dx +\Lambda|\Omega_v|$ for large $\Lambda$ with a boundary datum $g \ge 0$. In particular, in the case $g>0$, we show graphicality of the free boundary over $\partial D$ and obtain a second order asymptotic expansion in $\Lambda$ of the graph.
