## Abstract For a large class of pseudo‐differential operators with a negative definite symbol __q__(__x__, ξ) in the sense of Hoh and for a large family of __x__‐dependent Bernstein functions __f__(__x__, ·) we prove that the pseudo‐differential operator with symbol −__f__(__x__, __q__(__x__, ξ))
The aim of this paper is to define functions of several commuting and non-commuting self-adjoint pseudo-differential operators of non-positive order, by means of the H. Weyl formula Given 1<p< , the pseudo-differential operators under consideration belong to the Ho rmander class L m \, $ , m &n(1&\
