I'm sorry my ignorance, I don't know very much about mathematical magazines. I'm finishing my master degree in pure mathematics and I'm looking for mathematical magazines which could improve my undergraduate mathematical knowledge and in the same time help me to review the undergraduate contents.
After years studying pure mathematics I miss something to put all this knowledge altogether to solve interesting problems as for example a proof of the fundamental theorem of algebra using some basic analysis theorem or a simple proof using basic category theory of a known theorem in analysis or topology (undergraduate level). I would like something which can be read by an average mathematical bachelor (in pure mathematics).
I think this will enhance my mathematical creativity and see how mathematics can be beautiful.
I found this magazine, I don't if it's what I'm looking for: http://www.maa.org/publications/periodicals/college-mathematics-journal/college-mathematics-journal-contents-january-2014
Anyway, are there another ones? can be in French, Spanish or English.
