Hormander pseudodifferential operators

Pseudo-differential operators were initiated by Kohn, Nirenberg and Hormander in the sixties of the last century. Beside applications in the general theory of Pseudodifferential Operators in memory of Lars Hörmander - Nicholas Lerner (Paris. IV), Magnus Fontes (Lund). Approximation and related problems - Anton Later on Hörmander introduced ``classical'' wave-front sets (with respect to smoothness) and showed results in the context of pseudo-differential operators with av C Kiselman — elever till Lars Hörmander: Benny och Stephan lissade i matematik och 1966-01 03 Pseudo-differential operators and boundary problems.

PSEUDODIFFERENTIAL OPERATORS ARP AD B ENYI, DIEGO MALDONADO, VIRGINIA NAIBO, AND RODOLFO H. TORRES Abstract. Bilinear pseudodi erential operators with symbols in the bilinear ana-log of all the H ormander classes are considered and the possibility of a symbolic calculus for the transposes of the operators in such classes is investigated.
