Hi everyone So this year I’m starting my masters degree with a strong focus on geometry and GR. Since I’m transitioning from CS + Maths degree to just a Maths masters, I didn’t take any pure maths classes such as real analysis, topology and group theory. I only took one class in vector calculus, general relativity and quantum mechanics, the rest of my classes were discrete maths such as combinatorics, computational game theory, stats ect. The background needed for the unusual classes I just learnt that through the summer. I’m currently on a gap year and I managed to self study topology, real analysis, multivariable calculus ( rigorously now not just grad div curl ) and curved and surfaces ( up to gauss bonnet theorem) since I never took these classes during undergrad. I’ve encountered group theory before but it was just a little bit on a combinatorics class, I wasn’t very good at it.…
