We had submitted a research paper (graph theory related), which included a set of theorems, lemma, and proofs, to an international Mathematics conference around 2 months back.
The decision on our manuscript has come just a couple of days back. The decision is 'rejected'. However, we do not understand why there were no comments associated with the decision.
We are not worried about the rejection, rather, we are worried about what are the possible comments for the decision so that we can probably improve our work to fit in next venue (journal or conference).
We have emailed a few times to the conference chair about the comments; however, not heard anything great.
Does anyone here with this type of experiences? Is it really possible that they rejected the manuscript without peer-review?
