Abstract: The Dirichlet problem

$\displaystyle -\textup {div}(\vert\nabla u\vert^{p-2}\nabla u)=0 \ $$\displaystyle \mbox { in } \ \Omega , \ u\big \vert _{\partial \Omega }=f, $

is considered in the exterior of an $ n$-dimensional paraboloid, $ p\in (1,n)$. The space of the traces $ u\big \vert _\Gamma $ on the boundary of the paraboloid for functions $ u$ in the class $ L_p^1$ is described explicitly. This implies necessary and sufficient conditions for the existence and uniqueness of a solution to the Dirichlet problem.
