1.8.2 The Flowing Point of Axial Light
First, we consider the familiar group comprised of the -type Lie algebra from
where is defined as the group generator's rotation axis, and the bottom right matrix rotates in the -plane. Mathematically, a zero-dimensional point is a coordinate in space, and we define as the coordinates of the vertices of the equilateral triangle at a calculation time , which are located on the boundary of the unit ball defined by the symmetry up . The identity coordinate vector, , is then defined as
Next, we have the group generator acting on by taking the product
where the group generator has acted on the coordinate , giving each dimension a waveform signature for some chosen angular frequency To differentiate between the axis and the rotating planes in the product above, we have kept the axis portion of the vector result as , while expanding the values in the planes where the rotation occurs as respectively. We have act again on the vector result now defined as , finding
where the vector waveforms have advanced a distance of radians in complex space. The vital point to note is that the waveform vector contains information on a coordinate location in complex space, while the group generator includes the formal frequency and how the coordinate moves in complex space. Seeing how these two forms differ in their information content is a significant step towards understanding universal dynamics on the quantum level, which explicitly states that is the location in complex space, and defines how moves in that complex space. This is analogous to quantum mechanics' position and momentum and the implied uncertainty principle. We express this evolving system of matrix-vector products as
for , where signifies how changes over a calculative time, taking the form
Since , we can express our coordinate vector in the equivalent form
which enables us to express as
showing us how the position evolves in time for the wavefunction.
Before we choose a value for the angular velocity and proceed to study how the forms evolve, we need to consider the geometric arrangement of the axes of the group's geometric structure, and show how the real cosine and imaginary sine waves project orthogonally in their respective -planes.

blue waves are waves from the -plane, and red waves are waves from the -plane.
In the figure above, the orientation of each respective disc's real and imaginary axes, for which the individual trigonometric functions project back onto, is color-coordinated. We take the example of the red cosine wave from the -plane, its real values project back onto the real-valued the red disc's axis portion also travels in the direction of the -axis along with the green imaginary sine wave, where the radian rotation around the -axis orthogonally relates these waves. Important to grasp is that when considering the spatial direction of propagation for these two vectors, they travel in the same direction, albeit they are radians out of phase with one another, with one imaginary and the other real. We compare this to the propagation of the blue real cosine wave along the -axis, to find that it travels in a plane orthogonal to the previously mentioned waveforms.
The next issue that we consider is the logarithm function itself in complex space; by taking the example for the function , with and , its logarithm would typically be calculated as follows
The groups presented in this book have all been assumed to be bijective, meaning that each element of a set is paired one-to-one with the element of another set, and the other elements pair with exactly one element of the first set, leaving no elements unpaired. Bijectivity indeed holds if we restrict the domain of the exponential function to a branch of , avoiding any numbers in the domain differing by an integer multiple of , where we have been restricting the domains of our groups to the logarithm's principal value. We say that the bijectivity of a group is the required combination that all the elements are both injective and surjective. For a function/group to be injective, it must meet the requirement that the elements map in a one-to-one correspondence, and for that to occur, the function/group must be invertible. A surjective function maps an element of its domain to every element of the other function's domain in a one directional manner.
The way we calculated the previous logarithm , would fail in this injective requirement, as would the groups that have been defined in this book if the elements in their domains extended beyond the principal value of the logarithm. Describing mathematically cohesive dynamical systems requires that the complex logarithm is not restricted to the domain of the principal value. As a complex system evolves in a defined geometric spacetime, it travels in both imaginary and real spaces simultaneously, and this propagation in complex spaces requires extending beyond the principal value's domain. Maintaining injectivity brings us to the realization that the imaginary parts of our defined groups must exist on non-compact Riemann surfaces. To detail what this entails, we take our group generator example, , as it evolves in time,
for which injectivity would be compromised for the complex logarithm mapping when we find values of , since for , which would repeat for all following variables of the form, , for
The Riemann surface is often presented as an elegant solution to the injectivity problem that exists for the complex logarithm function. Still, we would argue that it should not be suggested as a workaround. Instead, it should be considered the correct way to depict the evolving complex functions and complex group functions in their Lie algebra forms and their exponentially mapped Lie group forms.

In the figure above, as the complex number moves around the origin, the imaginary values go up or down depending on the direction of rotation. A complete rotation of the complex unit circle by radians will increase the imaginary number's position along the vertical axis by when rotating in the positive direction. It decreases the position by the same amount when traveling in the negative direction.
We now return to the example, setting the angular frequency variable equal to where becomes
then let the system
evolve from to In doing so, we find the following set of thirteen coordinate vectors, which represents the system over the calculative time intervals
The axis of our group runs along the -axis, whose values are in the first row of each vector and represent the non-compact Riemann surface of the evolving flowing point. We note that the axis entry of the last vector has traveled radians along the vertical axis of the Riemann surface.
We orientate the reader to the position of the initial vector in the following figure, which is the black triangle with vertices located at values of along the -axes, and large colored arrows indicate the direction of propagation for each of the triangle's vertices and the relation to the complex plane it orients in.

As presented in Figure 1.8.1, the imaginary sine wave in green propagates along the real -axis, as does the red real cosine wave orientated radians clockwise about the real -axis. Alternatively, the blue real cosine wave propagates in an orientation aligned with the real -axis. We consider the direction of propagation for each as oriented vectors and plot the flowing point system,
in the figure below, it travels a distance of radians along the -axis in real space.

for , the magnetic field, and for , the imaginary-valued pilot wave in green.
Dynamically, the plot shows a propagation consistent with electromagnetic radiation, evidenced by the transverse waves formed by the oscillations of the real-valued and cosine waveforms, which are perpendicularly oriented to the direction of travel. The red cosine wave, we define to represent the electric field , and the blue cosine wave, the magnetic field . In this ideal system, we find that these and fields are in phase synchrony, where they reach maxima and minima at the same points in space along the -axis, and are in a fixed ratio of strength, all consistent with Maxwell's equations in a dissipation-less system. In a region without charges or currents, Maxwell's equations in differential form reduce to the following
where and represent the divergence of the electric and magnetic fields, which are zero in our example system, and and represent the curl of the electric and magnetic fields. Mathematically, curl defines the infinitesimal rotation of a vector field, while divergence defines the outward flux of a vector field as a volume density. The universal constants represent the permeability of free space and the permittivity of free space, which are related to the speed of light by the equality
and has the dimensions of
In addition to its consistency with electromagnetic radiation, what stands out about the flowing point system along the real-axis is the presence of a pilot wave in the form of the waveform. This pilot wave has a directional vector that sweeps back and forth as the flowing point travels in space, embodying the mathematical representation of the non-compact Riemann surface for the imaginary multi-valued portion of the -axis function. Its presence forms a central crux of the quantum and waveform discourse we will undertake in the physics volume Arithmoí series, particularly its application to hidden variables.
The flowing point that travels along the real -axis represents only half of what the system comprises, while the other half is its companion wave traveling along the imaginary -axis.

As mentioned in the previous section, perceived light in the electromagnetic form moves about the axes and asymptotes in complex space. This flowing point example moves along defined axes in complex space and is fitting for the manner in which light moves. When traveling along the axes, it does not experience the hyperbolic geometry that defines the spacetime constraints that massive objects experience.
