摘要
Our concern is the computation of optimal shapes in problems involving (-Delta)(1/2). We focus on the energy J(Omega) associated to the solution u(Omega) of the basic Dirichlet problem (-Delta)(1/2) u(Omega) = 1 in Omega, u = 0 in Omega(c). We show that regular minimizers Omega of this energy under a volume constraint are disks. Our proof goes through the explicit computation of the shape derivative (that seems to be completely new in the fractional context), and a refined adaptation of the moving plane method.
