Hypothetically, if I had an idea to improve an algorithm/theorem but
- I wasn't sure it was correct, or
- I wasn't sure it was significant or meaningful or hasn't already been published in a different form/somewhere else already or wasn't sure where to submit something like this .
is there somewhere I could submit a manuscript first privately to secure any intellectual property rights while I think about whether it is worth submitting or trying to do some more work on this and try to understand the field a bit better?
