Space-time `bonds', electromagnetism and graphs (Q1095955)

By assuming familiar relational properties of local, stratified space- time measurements and using simple graph symmetries, the laws of electromagnetism follow in their relativistic, four-dimensional form without invoking Lorentz transformations. This suggests that the topological compactification of pregeometric space-time points may be achieved through the laws of electromagnetism. The results are in agreement with those obtained using Lorentz transformations, spinors and forms.
