Complex Plane Dimension Number

AI Thread Summary
The discussion centers on the relationship between the complex plane and dimensions in physics, particularly in the context of complex number theory. Complex numbers are represented on a plane with real and imaginary axes, leading to the idea of an 'imaginary dimension.' However, this concept is distinct from the physical dimensions in theories like brane theory, which involve measurable units of space and time. Visualizing complex functions typically requires four dimensions due to their two-dimensional domain and range, resulting in three-dimensional surface plots. The distinction between mathematical abstractions and physical dimensions is emphasized, highlighting the complexity of integrating these concepts.

What dimension between space-time and 11 Dimensions is allocated to the complex plane 'visualized' and used in complex number theory?

Complex numbers are used in every branch of maths and physics, based on an imaginary complex plane, z = x +iy where y is an imaginary axis and i^2=-1. - It's another Dimension, the imaginary '5th' dimension.

In the current theories, what is name or number of is this dimension apart from the obvious 'imaginary dimension' - what number is it given?

You seem to be mixing up several concepts in physics and mathematics
that are different.

To properly visualize a complex function like f(z) = z^\frac{2}{3},
you would like 4 dimensions because the domain of the function is two-dimensions
and so is the range. This can't be done easily, so people usually plot |f(z)| which
is a scalar against z which is two dimensional. The result is a three-dimensional
surface plot.
 
What dimension between space-time and 11 Dimensions is allocated to the complex plane 'visualized' and used in complex number theory?
You are mixing up two different (although similar in some ways) concepts. The 11 dimensions of brane theory are physical dimensions, like space and time. The complex plane is a mathematical abstraction. One obvious difference is that for physical dimensions the numbers are in units of length or time, which can be changed (like from feet to meters). The numbers in the complex plane are absolute, e.g. 1 is 1 and nothing else - there is no concept of feet or seconds.
 
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...
