Blow-up solutions for the steady state of the Keller-Segel system on Riemann surfaces
Mohameden Ahmedou, Thomas Bartsch, Zhengni Hu
We study the following Neumann boundary problem related to the stationary solutions of the Keller-Segel system, a basic model of chemotaxis phenomena: \[ \left\{\begin{array}{ll} -…
Partial Blow-up Phenomena in the Toda System on Riemann Surfaces
Zhengni Hu, Mohameden Ahmedou, Thomas Bartsch
This work studies the partial blow-up phenomena for the Toda system on compact Riemann surfaces with smooth boundary. We consider the following coupled Liouville system wit…
Blow-up solutions for mean field equations with Neumann boundary conditions on Riemann surfaces
Zhengni Hu, Thomas Bartsch, Mohameden Ahmedou
On a compact Riemann surface with a smooth boundary , we consider the following mean field equations with Neumann boundary conditions: $$ -Δ_g u = λ\left(\frac…
Normalized solutions for nonlinear Schrödinger systems
Thomas Bartsch, Louis Jeanjean
We consider the existence of \emph{normalized} solutions in for systems of nonlinear Schrödinger equations which appear in models for binary mixtures o…
