Coming from an unknown university, is it possible to publish a good research paper in a good journal? Suppose someone is pursuing PhD in mathematics from a third class university and their supervisor has little knowledge about their own field. Is it possible to publish a good research paper in good journal?
Yes, it is possible. The institution doesn't matter. The advisor doesn't matter. What matters is the content (and correctness) of the paper, along with a judgement about its &quot;novelty&quot;. Those judgements will be made by reviewers and editors, independent of where the paper originates.
Good writing helps, of course.
