Geographer need a look at the Science of Spread (SOS). SOS can be directly connected to:
- Percolation science in Physics — one of the least understood physics
- Spatial Diffusion has been around but not developed fully in mathematical terms
- Spatial econometrics provides a weak basis for the dynamics of spread (heteroscedastic, ergodicity, non-stationarity)
- Network science (trying to connect with percolation physics)
- Mathematics of R0, backward bifurcation and hysteresis
- Mathematics of nonlinear dynamics (Strogatz)
- Mathematics of random networks (Strogatz)
- Information Theory (Hidalgo)
- Matrix as graphs (https://www.math3ma.com/blog/matrices-probability-graphs)
