Abstract
In this paper, we obtain the stability of isoperimetric inequalities with respect to the concentrate topology. The concentration topology is weaker than the \(\square \)-topology which is like the weak topology. As an application, we obtain isoperimetric inequalities on the non-discrete n-dimensional \(l^1\)-cube and \(l^1\)-torus by taking the limits of isoperimetric inequalities of discrete \(l^1\)-cubes and \(l^1\)-torus. The method of this paper builds on by introducing an \(\varepsilon \)-relaxed (iso-)Lipschitz order.
