A pseudo differential operator which shifts the wave front set

Author:

Parenti Cesare,Rodino Luigi

Abstract

The note concerns pseudo differential operators in the classes L ρ , 1 m , 0 > ρ 1 L_{\rho ,1}^m,0 > \rho \leqslant 1 . These operators are pseudo-local, but they can displace the wave front set of distributions, as we show by means of an example in L 1 , 1 0 L_{1,1}^0 .
