Do you know the Complex Plane?
Quaternions aren't such a pain!
Do you sing soliloquies
Concerning Reimann Geometries
Of balancing your Tensors,
Spinors and Complex Vectors?
Phase Spaces! Hilbert Spaces!
Oh, so many, many wacky places!



This is an open-ended thread dedicated to the discussion of various spaces used by physicists and mathematicians.

"Torture him, that's a good idea..."
 
Do you mean that we should discuss different states of matter, that are described by physicists and mathematicians? Or do you mean different concepts of space itself, altogether?
 
I mean different spaces. The real number line (denoted R) is a space. The complex plane (C) and the Euclidean plane (R^2) are other common examples of spaces.
 
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...
