Existence of multiple breathers for discrete nonlinear Schrodinger equations. <i>Electronic Journal of Differential Equations, 2019</i>(27), pp. 1-12.1072-6691https://hdl.handle.net/10877/14724In this article we study discrete nonlinear Schrödinger equations without periodicity assumptions. We show the existence of multiple solutions of the form u n e -iwt (called breathers) by using Clark's Theorem in critical point theory.Text12 pages1 file (.pdf)enAttribution 4.0 InternationalBreatherDiscrete nonlinear Schrödinger equationSubquadraticCritical pointArticleThis work is licensed under a Creative Commons Attribution 4.0 International License.
