Just corrected a misspelling. (sorry to Liviu Nicolaescu)

| Feb 9, 2012 at 13:45 | comment | added | Liviu Nicolaescu | If $f$ has compact support, then $f(P)$ is smoothing so the principal symbol is $0$. Also, Theorem 8.7 that you mention does not seem to cover Seeley's construction of complex powers of an elliptic operators. Taylor's approach does. Maybe the compact support condition is not needed? | |
