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 ...
A simple proof of Kotake-Narasimhan theorem in some classes of ultradifferentiable functions

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

[EN] We give a simple proof of a general theorem of Kotake-Narasimhan for elliptic operators in the setting of ultradifferentiable functions in the sense of Braun, Meise and Taylor. We follow the ideas of Komatsu. Based ...
