What math background is needed for self-studying quantum mechanics?

Click For Summary

Discussion Overview

The discussion revolves around the mathematical background necessary for self-studying quantum mechanics. Participants share their existing knowledge and seek recommendations for foundational mathematics and resources relevant to the study of quantum mechanics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant mentions having a background in differential calculus, differential equations, complex numbers, and probability calculus, and seeks advice on additional mathematical knowledge needed for quantum mechanics.
  • Another participant suggests that knowledge of linear algebra, particularly vector spaces and matrices, is essential and sufficient as a mathematical prerequisite to begin studying quantum mechanics.
  • A participant who has studied quantum mechanics indicates that core mathematical tools include calculus (especially integration) and linear algebra, and emphasizes the importance of being familiar with mathematical proofs for understanding the material.
  • It is noted that while differential equations enhance understanding, they may not be directly necessary for solving many problems in quantum mechanics, although they appear more frequently in proofs.

Areas of Agreement / Disagreement

Participants generally agree on the importance of linear algebra and calculus as foundational mathematics for quantum mechanics. However, there are varying opinions on the necessity of differential equations, with some suggesting they are beneficial but not essential for problem-solving.

Contextual Notes

Some assumptions about the level of familiarity with mathematical proofs and specific mathematical techniques are not explicitly stated, which may affect the applicability of the advice given.

Who May Find This Useful

This discussion may be useful for individuals interested in self-studying quantum mechanics, particularly those with a background in mathematics or related fields who are seeking guidance on the necessary mathematical foundations.

Hi folk, I have intention to study quantum mechanics as self-educated and so not as exam material. In order to do that, I wold know which are fundamental mathematics knowledge that one should need? I've a bachelor degree in computer science engineering and so I already have knowledge about differential calculus, differential equation, complex number, probability calculus and knowledge in physics and in particular classic physics like mechanics, electromagnetism. Could you recommend some books?
Thanks in advance. :wink:

I've gone through introductory QM (book by Griffiths) and I would say that the core mathematical tools used are calculus (namely integration) and linear algebra.

Of course if you are going to go through the proofs in the book you will need to be somewhat familiar with math proofs in general. Many of the problems both in the book and on our homework revolved around doing integrations, be comfortable with substitutions/integration by parts/etc.

Differential equations will greatly increase your understanding of the material, however many of the problems do not directly need it. It shows up much more in the proofs themselves.
