[Abstract-pdf]

Let $B_1$ be the open unit ball in $\mathbf{R}^3$ and let $20$ such that for each $\alpha\geq \alpha_0$, there exist at least $m$ nonradial positive solutions of $$ -\Delta u = |x|^\alpha |u(x)|^{p-2}u(x) \quad\text{in $B_1$,}\qquad u = 0 \quad\text{on $\partial B_1$,} $$ which are mutually nonequivalent if $m\geq 2$.

Keywords: Henon equation, multiplicity of positive solutions, concentration compactness principle, Poincare's inequalities.
