Graph Theory: Pure or Applied?

AI Thread Summary
Graph theory encompasses both pure and applied mathematics, with its utility depending on individual usage. While some view it primarily as a theoretical discipline focused on proofs, others appreciate its practical applications. The discussion suggests classifying graph theory along a concrete/abstract axis, highlighting its visualizable elements. Its relative independence from other mathematical branches allows beginners to engage with the subject without extensive prior knowledge. Ultimately, graph theory's dual nature and accessibility contribute to its appeal in both theoretical and practical contexts.

Hi

Is graph theory a more pure or applied subject?

I thought it was pure but now I am confusing myself because it has so many applications.

Thanks

It is both a theoretical and applied subject. You will decide how you'll use it. You can construct proofs and/or you can experiment with numerous graphs, their properties and their application. but a theoretical background is a must
 
I'd say pure. When I took graph theory, it was all about proving stuff about graphs (which is far from easy!).
 
I have dabbled in it both for fascination of 'pure' aspects and for some applications.

Would it be useful to classify it not by, or not only by, the pure/applied axis but along the concrete/abstract axis. It no doubt has abstract aspects, but it is often about perfectly 'concretely' visualisable things, whether they are useful or not and they always might be - a bit like 2 and 3D Euclidean geometry. Is that not one nice thing about it - for some of us?

Is not another nice aspect that it is relatively independent of other branches of mathematics, so a beginner can go quite far without a vast mathematical background?
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
