review text: Der Autor zeigt: Die Anzahl der positiven nichtäquivalenten nichtrotationssymmetrischen Lösungen von \(-\Delta u-u^ p=0\) in Ringgebieten unter Dirichlet Nullrandbedingungen strebt gegen \(\infty\), wenn der äußere Kugelradius gegen \(\infty\) geht. Ringgebiete zeigen somit ein deutlich anderes Verhalten als die Kugel.
