Esposito, Pierpaolo; Wei, Juncheng Non-simple blow-up solutions for the Neumann two-dimensional sinh-Gordon equation. (English) Zbl 1169.35049 Calc. Var. Partial Differ. Equ. 34, No. 3, 341-375 (2009). The authors prove that there exists small \(\rho_0 > 0\) such that for any \(0 < \rho \leq \rho_0\) the problem \[ -\Delta u = \rho^2 \bigg(e^u - \frac{1}{\pi}\int_B e^u\bigg)- \rho^2 \bigg(e^{-u} -\frac{1}{\pi}\int_B e^{-u}\bigg) \]in the unit two-dimensional ball \(B\) and \[ \frac{\partial u}{\partial \nu} = 0 \]on \(\partial B\) has a solution \(u_\rho\) such that as \(\rho \to 0\) \[ \rho^2 e^{u_\rho} \to 8\pi \delta(x), \qquad \rho^2 e^{-u_\rho} \to 24\pi \delta(x) \]hold weakly in the sense of measure on \(\overline{B}\).Therewith they present the first nontrivial example of non-simple blow-up of solutions of \(\sinh\)-Gordon equations and partially answered a question posed by J. Jost, G. Wang, D. Ye and C. Zhou [Calc. Var. Partial Differ. Equ. 31, No. 2, 263–276 (2008; Zbl 1137.35061)]. Reviewer: Iskander A.
