Asymptotics for elliptic equations involving critical growth. (English) Zbl 0685.35013
Partial differential equations and the calculus of variations. Essays in Honor of Ennio De Giorgi, 149-192 (1989).
[For the entire collection see Zbl 0671.00007.]
The author considers the problem \[ -\Delta u_{\epsilon}=\lambda u_{\epsilon}+3u_{\epsilon}^{5-\epsilon},\quad u_{\epsilon}>0 \] with 0 boundary data in a ball of \(R^ 3.\)
The asymptotic behaviour of \(u_{\epsilon}\) as \(\epsilon\) \(\to 0\) is studied for \(0\leq \lambda <\pi^ 2/4\) by methods of PDE.
