A characterization of the wave front set defined by the iterates of an operator with constant coefficients

Boiti, Chiara; Jornet Casanova, David (Springer-Verlag, 2017)

[EN] We characterize the wave front set WF*P (u) with respect to the iterates of a linear partial differential operator with constant coefficients of a classical distribution u is an element of D '(Omega), Omega an open ...
Wave front sets for ultradistribution solutions of linear partial differential operators with coefficients in non-quasianalytic classes

Albanese, Angela Ama; Jornet Casanova, David; Oliaro, Alessandro (Wiley-VCH Verlag, 2012-03)

We prove the following inclusion WF*(u)⊂ WF*(Pu)∪ Σ, u∈ε′* (Ω) where WF* denotes the non-quasianalytic Beurling or Roumieu wave front set, Ω is an open subset of R{double-struck} n, P is a linear partial differential ...
