In the first part of the paper we study the minimal and maximal extension of a class of weighted pseudodifferential operators in the Fréchet spaceL loc p ( Ω ) . In the second one non homogeneous microlocal properties are introduced and propagation of Sobolev singularities for solutions to (pseudo)differential equations is given. For both the arguments actual examples are provided.
