L p -boundedness for pseudodifferential operators with non-smooth symbols and applications

Starting from a general formulation of the characterization by dyadic crowns of Sobolev spaces, the authors give a result of L p continuity for pseudodifferential operators whose symbol a(x,ξ) is non smooth with respect to x and whose derivatives with respect to ξ have a decay of order ρ with 0 < ρ 1 . The algebra property for some classes of weighted Sobolev spaces is proved and an application to multi - quasi - elliptic semilinear equations is given.
