Non-Kirchhoff Vertices and NLS Ground States on graphs

Analysis of PDEs 2024-07-31 v2

Abstract

We review some recent results and announce some new ones on the problem of the existence of ground states for the Nonlinear Schr\"odinger Equation on graphs endowed with vertices where the matching condition, instead of being free (or Kirchhoff's), is non-trivially interacting. In this category fall Dirac's delta conditions, delta prime, F\"ul\"op-Tsutsui, and others.
