Is the trace tag supposed to be used for questions about the trace operator from Sobolev theory (analysis)?
I was going to de-tag "trace" from a question, but it seems like it's not the first time this happened,
- Trace Theorem: a question about Evans' proof
- A question about a detail in the proof of trace zero theorem Evans
- Trace theorems and Sobolev Spaces in unbounded domains
The description of the trace tag says it can be about the "trace of functions", but its quite far off from the other meanings of "trace" in mathematics, but I suppose it would help someone search, e.g. if they search for a combination of tags "trace" with "pde". Should I let it be?
This question has been almost asked before here, but with no answer: A sufficiently general tag wiki for "trace"?
