Abstract
We study solutions for the Hodge laplace equation \(\Delta u=\omega \) on p forms with \(\displaystyle L^{r}\) estimates for \(\displaystyle r>1.\) Our main hypothesis is that \(\Delta \) has a spectral gap in \(\displaystyle L^{2}.\) We use this to get non classical \(\displaystyle L^{r}\) Hodge decomposition theorems. An interesting feature is that to prove these decompositions we never use the boundedness of the Riesz transforms in \(\displaystyle L^{s}.\) These results are based on a generalisation of the Raising Steps Method to complete non compact Riemannian manifolds.
