| Sep 20, 2011 at 18:54 | comment | added | Deane Yang | I don't think what I suggest above works for a pseudodifferential operator, but it does work for a differential operator. But if you know how to define what a pesudodifferential operator is without using co-ordinates, that might provide a hint on how to isolate the symbol from the operator. | |
| Sep 20, 2011 at 18:44 | comment | added | Deane Yang | First, do you know how to define a pseudodifferential operator without using local co-ordinates? That seems like the hardest step to me. I haven't tried to work out details, but it seems possible to me that you can then define the symbol by studying how the operator acts on functions that vanish at a point to the appropriate order modulo those that vanish one order higher. | |
