Sufficient Conditions for Solvability of Operators of Subprincipal Type
Nils Dencker
In this paper we show that condition on the subprincipal symbol is sufficient for local solvability of linear pseudodifferential operators of real subprin…
Solvability of subprincipal type operators
Nils Dencker
In this paper we consider the solvability of pseudodifferential operators in the case when the principal symbol vanishes of order at a nonradial involutive manifold $Σ_2…
Solvability and limit complex bicharacteristics
Nils Dencker
We shall study the solvability of pseudodifferential operators which are not of principal type. The operator will have complex principal symbol satisfying condition () and we sh…
Operators of subprincipal type
Nils Dencker
In this paper we consider the solvability of pseudodifferential operators when the principal symbol vanishes of at least second order at a non-radial involutive manifold . We…
Solvability and limit bicharacteristics
Nils Dencker
We shall study the solvability of pseudodifferential operators which are not of principal type. The operator will have real principal symbol and we shall consider the limits of bic…
On the microlocal properties of the range of systems of principal type
Nils Dencker, Jens Wittsten
The purpose of this paper is to study microlocal conditions for inclusion relations between the ranges of square systems of pseudodifferential operators which fail to be locally so…
