| Jun 18, 2016 at 2:10 | comment | added | Pedro Lauridsen Ribeiro | I would add between (2) and (3) the introduction of the symbolic calculus of pseudos by Kohn and Nirenberg (1964 - classical, polyhomogeneous symbols of type $(1,0)$) and Hörmander (1965 - standard symbols of type $(\rho,\delta)$), as Deane Yang remarked in his answer (the year difference is just a formal matter- as timur commented there, both works appeared in the same volume of CPAM). Another addition would be the Hörmander-Weyl symbolic calculus (1979) after a much earlier idea of Weyl (1928) in the context of quantum mechanics, generalizing the symbolic calculus of Beals and Fefferman. | |
