Blow-up solutions for mean field equations with non-quantized singularities on Riemann surfaces with boundary

Mohameden Ahmedou, Zhengni Hu, Miaomiao Zhu

We study mean field equations with singular sources on a compact Riemann surface with boundary , subject to homogeneous Neumann boundary conditions: \[ -Δ_g v = ρ\left( \fra…

Blow-up Solutions for General Toda Systems on Riemann Surfaces

Zhengni Hu, Miaomiao Zhu

In this paper, we study general Toda systems with homogeneous Neumann boundary conditions on Riemann surfaces. Assuming the surface satisfies the ``-symmetric'' condition, we co…

A degree-counting formula for a Keller-Segel equation on a surface with boundary

Mohameden Ahmedou, Zhengni Hu, Heming Wang

In this paper, we consider the following Keller-Segel equation on a compact Riemann surface with smooth boundary : \[ -Δ_g u = ρ\Big(\frac{V e^u}{\int_Σ V e^u \…

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} -…
