On p-harmonic maps and convex functions

Abstract
We prove that, in general, given a -harmonic map and a convex function , the composition is not -subharmonic. By assuming some rotational symmetry on manifolds and functions, we reduce the problem to an ordinary differential inequality. The key of the proof is an asymptotic estimate for the -harmonic map under suitable assumptions on the manifolds.
