Minimality via second variation for a nonlocal isoperimetric problem

E Acerbi, N Fusco, M Morini - Communications in Mathematical Physics, 2013 - Springer
We discuss the local minimality of certain configurations for a nonlocal isoperimetric problem
used to model microphase separation in diblock copolymer melts. We show that critical …

Local and Global Minimality Results for a Nonlocal Isoperimetric Problem on

M Bonacini, R Cristoferi - SIAM Journal on Mathematical Analysis, 2014 - SIAM
We consider a nonlocal isoperimetric problem defined in the whole space R^N, whose
nonlocal part is given by a Riesz potential with exponent α∈(0,N-1). We show that critical …

Droplet minimizers of an isoperimetric problem with long‐range interactions

M Cicalese, E Spadaro - Communications on Pure and Applied …, 2013 - Wiley Online Library
We give a detailed description of the geometry of single‐droplet patterns in a nonlocal
isoperimetric problem. In particular, we focus on the sharp interface limit of the Ohta …
