Abstract

The limits of families of stable solutions for the equation over radially symmetric domains with no-flux boundary conditions are discribed. Particular emphasis is placed on the characterization of points of discontinuity of these limits (interfaces) and on the description of the graph of for small . Sufficient conditions for existence of interfaces in terms of the temperature function, , are given. The analysis is more complete for families of global minimizers of the associated energy functional.

Résumé

On étudie les limites de familles de solutions stables de l’équation sur des domaines à symétrie radiale sans flux au bord. On s’attache particulièrement à caractériser les points de discontinuité de ces limites (interfaces) et à décrire le graphe de pour petit . On donne des conditions suffisantes sur la température T pour qu’il existe des interfaces. On analyse de manière plus approfondie les familles minimisant l’énergie totale.
