function of a complex variable

Basically, it is not too big in quantum mechanics.

, but for a person

physics

It is unreasonable for professional students not to understand complex variable functions. special

Residual theorem

It is very practical to calculate some integrals by contour integral.

The relationship between quantum mechanics and mathematical methods is still relatively close. The core part of mathematical method is

Mathematical equation

There are many in quantum mechanics.

equation

This is a mathematical equation.

Participate, such as solving.

linear

harmonic oscillator

Another example is the Hermite equation.

hydrogen atom

Problems in spherical harmonic equations, l-order regularity

Bessel equation

These equations are based on

series

solution

Solving is very complicated. There is a detailed solution process in the mathematical equation. Secondly, I think the mathematical method is to cultivate the physical process.

Descriptive ability, and

(e.g.

Variable separation method

, these are all must master).

Finally, my suggestion is that you don't have to master quantum mechanics completely to learn well.

methods of mathematical physics

Look back when you encounter related problems. Otherwise, it will take too much time to take the postgraduate entrance examination.

It won't involve too much complexity.

Want to engage in

theoretical research

If so, you should be familiar with the basic solution of the equation. You don't have to work it out completely by yourself, but you should be familiar with the process. Because this is
