A nonlinear Klein-Gordon equation on a star graph
Nataliia Goloshchapova
We study local well-posedness and orbital stability/instability of standing waves for a first order system associated with a nonlinear Klein-Gordon equation on a star graph. The pr…
On the standing waves of the NLS-log equation with point interaction on a star graph
Nataliia Goloshchapova
We study a nonlinear Schrödinger equation with logarithmic nonlinearity on a star graph . At the vertex an interaction occurs described by a boundary condition of delt…
On the orbital instability of excited states for the NLS equation with the -interaction on a star graph
Jaime Angulo Pava, Nataliia Goloshchapova
We study the nonlinear Schrödinger equation (NLS) on a star graph . At the vertex an interaction occurs described by a boundary condition of delta type with strength $…
Extension theory approach in the stability of the standing waves for the NLS equation with point interactions on a star graph
Jaime Angulo Pava, Nataliia Goloshchapova
The aim of this work is to demonstrate the effectiveness of the extension theory of symmetric operators in the investigation of the stability of standing waves for the nonlinear Sc…
Stability of standing waves for NLS-log equation with -interaction
Jaime Angulo Pava, Nataliia Goloshchapova
We study analytically the orbital stability of the standing waves with a peak-Gausson profile for a nonlinear logarithmic Schrödinger equation with -interaction (attractive and…
