Abstract

In this paper we study the following quantitative isoperimetric inequality in the plane: λ02(Ω)Cδ(Ω)\lambda_0^2(\Omega) \leq C \delta(\Omega) where δ\delta is the isoperimetric deficit and λ0\lambda_0 is the barycentric asymmetry. Our aim is to generalize some results obtained by B. Fuglede in \cite{Fu93Geometriae}. For that purpose, we consider the shape optimization problem: minimize the ratio δ(Ω)/λ02(Ω)\delta(\Omega)/\lambda_0^2(\Omega) in the class of compact connected sets and in the class of convex sets.
