ESAIM: Control, Optimisation and Calculus of Variations
In this paper we study the compact and convex sets K ⊆ Ω ⊆ ℝ2that minimize
∫ Ω dist ( x ,K ) d x + λ 1 Vol ( K ) + λ 2 Per ( K ) for some constantsλ1 and λ2, that could possibly be zero. We compute in particular the second order derivative of the functional and use it to exclude...
