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.

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...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
