Topological Charge
Definition
Topological Charge is the conserved integer-valued quantity Q⧝ that counts, over all positions of the Zero Substrate, the signs of the determinant of the static tension gradient; it stays constant from the Zero Substrate through all later evolution.
The book lists it among the conservation laws of the Zero Substrate, with Total Information, Energy-Momentum and substrate volume, and calls such conserved topological quantities cosmic DNA signatures: built from the static tension field before time begins, they carry the substrate's structure unchanged through every later transformation and so ensure structural continuity. It belongs to the pre-temporal geometry of section 5.5 together with the Dimensional Capacity Function and the Initial Metric Tensor. Among the book's testable predictions, Q⧝ should be conserved in particle decay processes observable in high-energy collisions.
The book writes Q⧝ = Σ_x sign(det(∇T_0(x))), where Q⧝ is the topological charge [∅], Σ_x the sum over all positions x, sign the sign function [∅], det the determinant [∅], ∇ the gradient operator [𝕃⁻¹] and T_0(x) the static tension at position x [𝕄·𝕃⁻¹·𝕋⁻²]. Taking signs removes all dimensions, so Q⧝ is [∅].
Topological Charge connects to Static Tension Vectors, Zero Substrate, Energy-Momentum, Total Information, Conservation Principles and Topological Containment.
