Hi, I have one spot remaining to take a pure math course, and I'm trying to decide between complex analysis and group theory. Although I've touched some of the basic of dealing with complex numbers in my physics/DE courses, they haven't gone in much depth into them beyond applications. On the other hand, my background in group theory is a bit weak (read: nonexistent). I am also a little uncertain on which area in physics (I'm a physics undergrad) I'd like to go into in the future, but I'm leaning towards topics in astronomy and possibly high-energy physics. Any insight you have on which course might be better to take in my situation would be greatly appreciated!
