Abstract:
The Paneitz operator is a fourth order differential
operator which arises in conformal geometry and satisfies a certain covariance property.
Associated to it is a fourth order curvature -- the \$Q\$-curvature.

We prove the existence of a continuum of conformal radially symmetric
complete metrics in hyperbolic space \$\mathbb{H}^n\$, \$n>4\$, all having
the same constant \$Q\$-curvature.

Moreover, similar results can be shown also for suitable non-constant
prescribed \$Q\$-curvature functions.

Keywords:
Paneitz equation, complete conformal metric, hyperbolic space, prescribed Q-curvature
