I realize that this question may be off-topic, but I do not know where else can I find a 'social media' where OR practitioners hang out. I am about to finish my math BSc. and about to do my masters. I am interested in learning more OR, so I would like to know which areas of mathematics are the most useful for OR?
Question: Which areas of mathematics should be strengthen in anticipation of doing OR? Strengthen can be understood as learning from a graduate text for subject X in the summer break.
- Linear Algebra. I haven't touched a more advanced linalg book, but I made a point to try to use it in my thesis. I don't have a more advanced knowledge but I know the undergraduate material pretty intimately by usage.
- Abstract Algebra. Took two courses, covered rigorously groups, rings, and fields.
- Graph theory. Fairly ahead of the standard graph theory classes math and cs students take (did ramsey theory, turan graphs), I just like the subject.
- Analysis. What you would expect to know of an undergraduate, rigorous single + multivar, rigorous real analysis, somewhat milder complex analysis (half of the class was complex analysis, the other half was intro to measure theory). In fact, I skipped a proper measure theory course, should I take this in my masters?
- Probability, statistics, stochastics. I did a course in each, and I am strong in them, but I don't know if they are that relevant to OR?
