报告摘要:
In this talk, we will first review recent advances in the analysis of noncompact quantum graphs, with a particular focus on nonlinear variational problems. We then study the nonlinear Dirac equation on such graphs under Kirchhoff-type vertex conditions. The associated action functional is strongly indefinite, and the Palais-Smale condition fails. To address these challenges, we employ recently developed critical point techniques to establish our existence results.
