My article was accepted for publication in European Journal of Pure and Applied Mathematics, but it didn’t compile with their LaTeX templates. After waiting a reasonable time until they would tackle the problem, I have withdrawn my article and sent it to another journal.
I would search for the bug in their LaTeX template myself, but I was a great LaTeX expert in the past, I have forgotten much of LaTeX tricks, as now I use TeXmacs to write my manuscript, I convert them to simple LaTeX only to send it to a publisher. So I have chosen not to attempt to resolve the problem with LaTeX but just to send it to an other journal.
