How much is (upper div) linear algebra and algebra needed for an applied math?

AI Thread Summary
Upper division courses in linear algebra and abstract algebra are highly recommended for students majoring in applied mathematics, especially those considering graduate school. While the applied math major only requires one semester of linear algebra (course 115A), taking additional courses in both linear and abstract algebra can significantly enhance understanding and competency in the field. Abstract algebra provides foundational knowledge on groups and homomorphisms, which are essential for grasping advanced mathematical concepts. Furthermore, advanced linear algebra is crucial for tackling higher-level topics such as partial differential equations (PDEs), ordinary differential equations (ODEs), and numerical methods. Overall, pursuing these upper division courses can better prepare students for the complexities of applied mathematics and graduate studies.

Hello, I'm doing a bit of course planning right now. I'm majoring in applied math, and I'm just wondering if upper division linear algebra and abstract algebra is needed to be competent as an applied mathematician (graduate school bound possibly)?

Here are the course descriptions. Algebra is a 3 quarter sequence, while Linear Algebra is a 2 quarter sequence. Algebra I requires LA I as a prerequisite.

110A. Algebra (4)
Lecture, three hours; discussion, one hour. Requisite: course 115A. Not open for credit to students with credit for course 117. Ring of integers, integral domains, fields, polynomial domains, unique factorization. P/NP or letter grading.

110B. Algebra (4)
Lecture, three hours; discussion, one hour. Requisite: course 110A or 117. Groups, structure of finite groups. P/NP or letter grading

110C. Algebra (4)
Lecture, three hours; discussion, one hour. Requisites: courses 110A, 110B. Field extensions, Galois theory, applications to geometric constructions, and solvability by radicals.

---------------------------------

115A. Linear Algebra (5)
Lecture, three hours; discussion, two hours. Requisite: course 33A. Techniques of proof, abstract vector spaces, linear transformations, and matrices; determinants; inner product spaces; eigenvector theory. P/NP or letter grading.

115B. Linear Algebra (4)
Lecture, three hours; discussion, one hour. Requisite: course 115A. Linear transformations, conjugate spaces, duality; theory of a single linear transformation, Jordan normal form; bilinear forms, quadratic forms; Euclidean and unitary spaces, symmetric skew and orthogonal linear transformations, polar decomposition. P/NP or letter grading.

---------------------------------

Note that the applied math major requires only 115A, and no algebra.

But of course I would be willing to go over the requirements if that will help me. Any suggestions?

You should at least take one semester of abstract algebra and a second semester of linear algebra (upper div LA). The abstract algebra would be good as an intro in knowing some basic things on the fundamentals of algebra (groups, homomorphisms, etc.). It's good to at least know what's out there, as well as knowing the basics for fields you aren't a specialist in. The upper div LA is quite necessary for applied math, especially if you want to delve into higher-level applied math (PDEs, ODEs, numerical methods, etc.).
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
