I do not know if this is the right place for this question. I am an undergraduate math student entering his junior year this coming fall, but I'd like to teach myself some math that is accessible to me giving my current knowledge. So far I have taken (all undergraduate):
a linear algebra course, a theory of ODE/dynamical system's course, a topology course that went up to basic algebraic topology (Which I did not understand a lot), and Calculus 1-3.
Next semester I am taking real analysis, numerical analysis, and intro probability theory.
So in essence my question is what topics could I self study over this summer?
