I don't know whether this is the appropriate place to ask my question but since there is no harm in asking, let me ask. My nephew, who is an undergraduate student, has sent a paper to the journal Notes on Number Theory and Discrete Mathematics about one month ago. Since it has been 1 month, he has tried to know the status of the paper by mailing the required person twice, but due to some unknown reason the person seems silent.
Does anyone know anything about the journal except the information that has been given to its website? What should my nephew do now?
