In this paper, the stability properties of these structures have been considered. It has been performed an analytical study for low-coupling solutions based upon the so called multibreather stability theorem previously developed by some of the authors [Physica D 180 235]. A numerical analysis confirms the analytical predictions and gives a detailed picture of the existence and stability properties for arbitrary frequency and coupling.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Computational physicsStatistical physics and nonlinear systemsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1088/1751-8113/44/3/035102https://idus.us.es/xmlui/handle/11441/24834
