What to study in mathematics after taking basic math courses?

Click For Summary

Discussion Overview

The discussion revolves around the next steps in mathematical study after completing basic courses, including calculus, differential equations, and linear algebra. Participants explore various advanced topics and fields, such as differential geometry, topology, and abstract algebra, while considering personal interests and backgrounds in mathematics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant expresses uncertainty about how to decide on future studies in mathematics and whether it is time to specialize.
  • Another participant suggests that it is too early to specialize and recommends exploring general topology, abstract algebra, and real/functional analysis, along with differential geometry.
  • A request for book recommendations on differential geometry is made, leading to suggestions of Spivak, Lee, and Do Carmo as suitable introductory texts.
  • Participants discuss the prerequisite knowledge needed for studying differential geometry, emphasizing the importance of a solid foundation in analysis, topology, and algebra.
  • One participant mentions that taking courses in number theory can provide insight into ongoing research areas, noting the connection to abstract algebra and its branches.
  • A later reply highlights the importance of having a strong background in relevant mathematical topics before tackling advanced subjects like differential geometry.
  • Another participant identifies themselves as an engineer with limited mathematical background, indicating a need for foundational knowledge in topology and manifolds.

Areas of Agreement / Disagreement

Participants generally agree that it is premature to specialize without further exploration of various mathematical fields. However, there are differing opinions on the specific topics and prerequisites necessary for advancing in mathematics.

Contextual Notes

Participants emphasize the importance of individual backgrounds and prior knowledge when considering advanced mathematical studies, indicating that recommendations may vary based on personal experience and interests.

Who May Find This Useful

This discussion may be useful for mathematics students or professionals seeking guidance on advanced topics to pursue after foundational courses, as well as those interested in understanding the pathways to specialization in mathematics.

I've taken differential,integral,multivariate calculus, DEQs, Introductory Linear Algebra, and am currently taking complex analysis and vector calculus (an extension of vector calc from multivariate). As a math student, how do you decide what to study after that? Is it time to specialize?

I don't have a broad road map of mathematics but I do know that I like to think about space, mappings, surfaces. How do mathematicians go about finding what they like to research/learn (either as a hobby or for their research)?

Not even close to specializing time. You should try reading some general topology, abstract algebra and maybe some real/functional analysis books. If surfaces sound interesting to you, then look into some differential geometry. Shop around and see what you like.
 
Hi jgens, can you recommend any books for differential geometry for beginner?
 
Depends on your background and where you want to go with the subject. I think that Spivak and Lee are great books to get a feel for manifolds and the very basics of differential geometry. Do Carmo is another popular alternative.

Is there any basic knowledge I need to know before studying differential geometry?
 
To OP, you are nowhere close to being able to specialize. Take two more years of general math, including more linear algebra, a couple semesters of analysis, some algebra, and a good topology course. You can always mix in stuff like intros to PDE, DG, graph theory, whatever here, but by no means should you specialize until you've tasted a sizable bit from each field.

What is your math background? Have you taken analysis, topology, algebra, a bit of algebraic topology, linear algebra, and how much of each? There are many places to start in Differential Geometry and Topology, but they all depend on your background. As mentioned already, if you have a mastery of the sophmore/junior courses associated with the above topics, you should probably be able to tackle Lee. However, it would be good to have a more 'intuitive' and elementary DG course first. DoCarmo is good. If you like physics, Nakahara is great.
 
You can usually see some on-going areas of research by taking some courses in number theory if you want to get a feel for some of the problems out there that is. You will likely need abstract algebra if you intend to go that route as well though. Many different things branch off abstract algebra, to name a few: algebraic geometry, algebraic number theory, algebraic topology.

Thanks for your advice. Actually I'm a engineer, the highest level of maths I have studied is engineering maths and numerical analysis. This is my first time heard about topology and manifold.
