Showing a solution of elliptic PDe is non-degenerate
Here I explain where the original problem is coming from, since it is quite possible I don't need what I am asking for.
I am interested in obtaining positive solutions of the equation $ -\Delta u( …

Showing a solution of elliptic PDe is non-degenerate
Dear Mathoverflowers:
I am interested in radial positive solutions of
$-\Delta u(r) = r^\alpha u(r)^p$ in the unit ball in $ R^N$ with $ u=0$ on the boundary.
Here $p>1$ and $ \alpha >0$. (There …
