Background for Analysis and Topology

AI Thread Summary
A foundational understanding of calculus, experience with proofs, and familiarity with sets are essential for learning Analysis and Topology. It is generally recommended to study analysis before topology, with a focus on metric spaces, which are often covered in analysis courses. Rigorous analysis texts, such as those by Aliprantis & Burkinshaw or Abbott, are suitable for self-learners. There is some confusion regarding the curriculum, as one participant noted that their school's real analysis course primarily covers metric spaces and topology, which is atypical since real analysis should also include differentiation, integrals, and series. The concept of "reconstruction" of the real numbers is typically addressed in real analysis but may also appear in set theory or abstract algebra courses, although the latter is considered unusual.

Hi!

I am a self-learner. What background knowledge is necessary to learn Analysis and Topology?
 
Physics news on Phys.org
Calculus, an experience with proofs and an experience with sets.

Personally, I would take analysis before you take topology. Make sure you know about metric spaces before topology (metric spaces are usually studied in analysis, but not always).

If you studied calculus from a rigorous book like Spivak, then you can take on a rigorous analysis book (like the excellent book by Aliprantis & Burkinshaw). Otherwise, the book "Understanding Analysis" by Abbott is very good.
 
Is it weird that my school's real analysis is a course on topology and metric space? I'm only first year but that's what my calculus teacher told me when i asked what real analysis was. He told me the course content for real analysis course at my school was metric space and topology.

I keep on hearing about "reconstruction" of the real numbers... but apparnetly that's done in abstract algebra and or set theory 3rd year course. Is this normal?

That's a bit weird. Metric spaces (and a little topology) are certainly part of real analysis, but real analysis should be much more then that. It should also deal with differentiation, integrals, series, etc. It's a bit weird if you only see topology in your real analysis course.

Reconstruction of the real numbers is very often done in real analysis, because it's important to know what the real numbers are exactly. It is extremely weird that you do this in abstract algebra, I never heard of such a thing before. It would fit in a set theory course though.
 
Bit Britain-specific but I was wondering, what's the best path to take for A-Levels out of the following (I know Y10 seems a bit early to be thinking about A-levels, but my choice will impact what I do this year/ in y11) I (almost) definitely want to do physics at University - so keep that in mind... The subjects that I'm almost definitely going to take are Maths, Further Maths and Physics, and I'm taking a fast track programme which means that I'll be taking AS computer science at the end...
After a year of thought, I decided to adjust my ratio for applying the US/EU(+UK) schools. I mostly focused on the US schools before, but things are getting complex and I found out that Europe is also a good place to study. I found some institutes that have professors with similar interests. But gaining the information is much harder than US schools (like you have to contact professors in advance etc). For your information, I have B.S. in engineering (low GPA: 3.2/4.0) in Asia - one SCI...
I graduated with a BSc in Physics in 2020. Since there were limited opportunities in my country (mostly teaching), I decided to improve my programming skills and began working in IT, first as a software engineer and later as a quality assurance engineer, where I’ve now spent about 3 years. While this career path has provided financial stability, I’ve realized that my excitement and passion aren’t really there, unlike what I felt when studying or doing research in physics. Working in IT...
