Recursive Density Evolution
Definition
Recursive Density Evolution is the cascade dynamics by which recursive density spreads, grows and decays over space and time, which the book holds responsible for the fractal patterns of large-scale cosmic structure.
The book states it as ∂ρℜ/∂t = D ∇² ρℜ + f(ρℜ) − γ ρℜ + η(x,t): the rate of change of recursive density combines a diffusion term, a growth function of the density itself, a decay term and a noise term. Its testable prediction is large-scale structure fractal patterns, measurable through multi-scale correlation analysis of galaxy distributions showing self-similar hierarchical structure formation. It carries forward the recursive density whose accumulation, in Recursive Density Accumulation, drives overflow and emergence.
It connects to Recursive Density Accumulation, Self-Organized Criticality Dynamics, Self-Organizing Criticality and Large-Scale Structure Correlations.
Mathematical Expression
From the book · Chapter 9 · The Ignition Moment — When Potential Becomes Reality
∂ρℜ/∂t = D ∇² ρℜ + f(ρℜ) - γ ρℜ + η(x,t) [kg/(m³·s)]
Where:
- ∂ρℜ/∂t [𝕄·𝕃⁻³·𝕋⁻¹] - time derivative of recursive density field
- ρℜ [𝕄·𝕃⁻³] - recursive density field
- D [𝕃²·𝕋⁻¹] - diffusion coefficient
- ∇² [𝕃⁻²] - Laplacian operator
- f(ρℜ) [𝕄·𝕃⁻³·𝕋⁻¹] - nonlinear growth function
- γ [𝕋⁻¹] - decay rate
- η(x,t) [𝕄·𝕃⁻³·𝕋⁻¹] - noise term
- x [𝕃] - spatial position
- t [𝕋] - time variable
