I'm beginning college winter semester, and am just curious what sort of math classes I would be most appropriate for understanding the mathematics behind quantum theory. I have several years background in cosmology and astronomy, however the subject of the quantum has just been to tantalizing to ignore. Mostly, I am interested in the probabilistic nature of things at the quantum scale, but beyond that I've been wondering what sort of math courses would most help me in solving probabilistic equations. My mathematics background as it stands now, consists of advanced algebra, some calculus courses, and I am now beginning to teach myself linear algebra. however, I am somewhat at a loss as to what courses would be most applicable to quantum mathematics. Was just wondering if anyone had some suggestions as to what I should consider taking in the near future.
