Abstract:
The $p$-energy of Sobolev mappings between Riemannian manifolds is studied, for each integer $p$ greater than two. We analyse the lower semicontinuous extension of the energy to currents. We then restrict to mappings with values into the $p$-sphere, by giving an explicit relaxed $p$-energy formula, whose proof depends on a strong density result. Finally, a related coarea formula is obtained.
