%0 Journal Article %T A limiting free boundary problem ruled by Aronsson's equation %A J. D. Rossi %A E. V. Teixeira %J Mathematics %D 2009 %I arXiv %X We study the behavior of $p$-Dirichlet optimal design problem with volume constraint for $p$ large. As the limit as $p$ goes to infinity, we find a limiting free boundary problem governed by the infinity-Laplacian operator. We establish a necessary and sufficient condition for uniqueness of the limiting problem and, under such a condition, we determine precisely the optimal configuration for the limiting problem. Finally, we establish convergence results for the free boundaries. %U http://arxiv.org/abs/0903.2274v2
