Geometry and structure for phenomena that refuse to stay in one discipline.

Start here for networks, information geometry, transport, emergence, and formal tools that cross domains.

★ Best entry point

Complex systems — the broadest map of cross-scale structure and emergence.

? Core questions

• Which mathematical language genuinely compresses biology, cognition, or agent behavior?
• When do information, transport, geometry, and network structure make different predictions?
• How should definitions, intuitions, examples, and speculative extensions be separated?

↗ Selected pathways

• Information: Entropy · Divergence
• Transport: Wasserstein distances / optimal transport · Entropic regularization
• Geometry: Surprisal / Fisher information / curvature
• Choice and interaction: Decision theory · Algorithmic game theory
• Frontier: Super-speculative math
