Blow-up analysis for nodal radial solutions in Moser-Trudinger critical equations in $R^2$

Massimo Grossi, Daisuke Naimen

In this paper we consider nodal radial solutions $u_{\epsilon }$ to the problem \[ \begin{cases} -Δu=λue^{u^2+|u|^{1+ε}}&\text{ in }B,\\ u=0&\text{ on }\partial B. \end{cases} \] and we stud…
