The raising steps method. Applications to the $\displaystyle L^{r}$ Hodge theory in a compact riemannian manifold.
Résumé
Let $X$ be a smooth manifold and $\displaystyle \Omega $
a domain in $\displaystyle X.$ The Raising Steps Method allows
to get from local results on solutions $u$ of equation $
Du=\omega $ global ones in $ \Omega .$
It was introduced in~\cite{AmarSt13} to get good estimates on
solutions of $\bar \partial $ equation in domains in a Stein manifold.
It is extended here to linear partial differential operator
of any finite order.
As a simple application we shall get a $\displaystyle L^{r}$
Hodge decomposition theorem for $p$ forms in a compact riemannian
manifold without boundary, and then we retrieve known results
of C. Scott by an entirely different method.
