Abstract

In this paper, we are concerned with the following elliptic equation (SCε){Δu=u4/(n2)u[ln(e+u)]ε in Ω,u=0 on Ω, ( SC_\varepsilon ) \qquad \begin{cases} -\Delta u = |u|^{4/(n-2)}u [\ln (e+|u|)]^\varepsilon & \hbox{ in } \Omega,\\ u = 0 & \hbox{ on }\partial \Omega, \end{cases} where Ω\Omega is a smooth bounded open domain in Rn, n3\mathbb{R}^n, \ n\geq 3 and ε>0\varepsilon >0. In Comm. Contemp. Math. (2003), Ben Ayed et al. showed that the slightly supercritical usual elliptic problem has no single peaked solution. Here we extend their result for problem (SCε)( SC_\varepsilon ) when ε\varepsilon is small enough, and that by assuming a new assumption.
