Abstract
We prove existence and uniqueness up to rescaling of positive radial entire solutions of supercritical semilinear biharmonic equations The proof is performed with a shooting method which uses the value of the second derivative at the origin as a parameter This method also enables us to find finite time blow up solutions Finally we study the convergence at infinity of smooth solutions towards the explicitly known singular solution It turns out that the convergence is different in space dimensions n ≤ 12 and n ≥ 13
