Qualitative analysis on the critical points of the Kirchhoff-Routh function
Francesca Gladiali, Massimo Grossi, Peng Luo +1
In this paper, we study the number of critical points of the Kirchhoff-Routh function \begin{equation*} \mathcal{KR}_D(x,y)=Λ_1^2\mathcal{R}_D(x)+Λ_2^2\mathcal{R}_D(y)-2Λ_1Λ_2G_D(x…

Morse index, topological degree and local uniqueness of multi-spikes solutions to the Lane-Emden problem in dimension two
Isabella Ianni, Peng Luo, Shusen Yan
We consider multi-spike positive solutions to the Lane-Emden problem in any bounded smooth planar domain and compute their Morse index, extending to the dimension classical t…
