Abstract:

We discuss conditions on a function $f$ under which the commutator $[P,f]$ of a pseudodifferential operator $P$ of order $m$ with the operation of multiplication by $f$ is an operator of order $m-r$ on various function spaces, namely Hölder-Zygmund spaces and $L^p$-Sobolev spaces, given $0<r<1$. We also establish an endpoint case involving $r=1$, and we extend the scope to all $r>0$ for a particularly significant case in 1 dimension.
