I will attempt to represent a symbol to a ps.d.o., using two bases and a lifting functional. The representation is based upon an invariance principle and conditions on the boundary, defined by first surfaces to the symbol.

Some remarks on Schr{\"o}dinger operators

The problem we consider is given a mixed model $F(\gamma) \rightarrow \gamma \rightarrow \tilde{\gamma}$ and a potential $\widehat{V}$ such that $\log \widehat{V} \in L^{1}$, to determine a movement
