Hi guys. It's almost time to choose my courses for this year. I'm torn between taking PDE's due to how important it is for physics, or complex analysis due to just liking pure maths. If I do well enough, I'm *possibly* looking to do further study in mathematical physics. I was thinking that if the PDE class is anything like the ODE class, I might be able to get away with just learning the material myself as I need it, when the time comes.

Comments appreciated. Also, does complex analysis have much application in physics?

ODEs are far simpler in my opinion to solve. While I enjoyed my PDE class what's called advanced engineering mathematics at my school, it was a pain compared to ODEs which are pretty easy to solve, especially after dealing with them in my engineering courses so much. PDE were useful when I took heat transfer, and fundamentals of nuclear engineering. Infinite series too

Generically speaking the classes are of comparable utility in physics. Choose whichever interests you more.

Eventually, you are going to need to take a course in both PDEs and complex analysis. In fact, I recommend that you take the complex analysis course first. Complex variables can be useful in solving certain PDEs, especially in the use of conformal mapping techniques for solving 2-D PDEs.

I would almost advise complex analysis before PDE's, though you should take both, because of the Fourier analysis that you may learn in PDE class.

Thanks for the replies everyone. I was leaning toward complex analysis and judging from the replies here, it wouldn't be a bad choice. So complex analysis it is!

What is the difference between PDE's and complex analysis in physics/math?

PDE's (partial differential equations) and complex analysis are two different mathematical approaches used in physics and mathematics. PDE's deal with equations involving functions of multiple variables and their partial derivatives, while complex analysis deals with functions of complex numbers and their derivatives. PDE's are used to model physical phenomena such as heat flow, wave propagation, and fluid dynamics, while complex analysis is used to study functions with complex inputs and outputs and their properties.

Which approach is more commonly used in physics/math?

Both PDE's and complex analysis are essential tools in physics and mathematics. In general, PDE's are more commonly used in physics because they are well-suited for modeling physical systems. However, complex analysis is also widely used in certain areas of physics, such as quantum mechanics and electromagnetism, where complex numbers are used to represent physical quantities.

What are the advantages of using PDE's over complex analysis in physics/math?

PDE's have the advantage of being able to model a wide range of physical systems, including those with complex boundary conditions and non-linear behavior. They also have a rich set of analytical and numerical methods for solving them, making them a powerful tool for studying real-world problems. Moreover, PDE's have a strong connection to geometry and topology, making them useful for understanding the underlying structure of a physical system.

What are the advantages of using complex analysis over PDE's in physics/math?

Complex analysis has the advantage of being able to deal with complex functions and their derivatives, which can often simplify mathematical expressions and calculations. In addition, many physical systems can be described using complex numbers, making complex analysis a natural approach for studying them. Complex analysis also has a strong connection to other areas of mathematics, such as number theory and algebra, making it a versatile tool for solving problems in physics and math.

Can PDE's and complex analysis be used together in physics/math?

Yes, PDE's and complex analysis can be used together in physics and math. In fact, many real-world problems require a combination of both approaches to fully understand and model them. For example, in fluid dynamics, PDE's are used to describe the flow of a fluid, while complex analysis is used to analyze the behavior of the fluid near singular points. In quantum mechanics, PDE's are used to describe the wave function of a particle, while complex analysis is used to study the behavior of the wave function in complex space.
