| Jun 9, 2018 at 3:24 | comment | added | geometricK | But, for instance, it is a non-trivial result of Seeley in the setting of a compact manifold that powers of elliptic operators are still pseudodifferential. I guess I'm asking a version of the question "does Seeley's result work in the non-compact setting?" | |
| Jun 8, 2018 at 18:50 | comment | added | Deane Yang | Yes. All of the operations used to define $A$ in terms of $D$ are well defined in the space of pseudodifferential operators. | |
