THE LOCAL SOLVABILITY OF A CLASS OF PSEUDO–DIFFERENTIAL EQUATIONS OF PRINCIPAL TYPE

Acta Mathematica Scientia, 1986
The local solvability of pseudo differential equations already have been mentioned by many authors, but in general, the pseudo differential operators which were discussed belong to \(S^ m_{10}\), and their principal symbols p(x,\(\xi)\) are homogeneous functions with respect to \(\xi\).

Semilinear pseudo-differential equations and travelling waves

2007
We consider semilinear perturbations of the SG-elliptic pseudodifferential equations. We prove for them a theorem on the regularity of the solutions in the functional frame of the Gelfand-Shilov classes. Applications are given to the study of travelling solitary waves.
