Prolog

• Line, surface & volume integrals in n-D space → Exterior forms• Time evolution of such integrals → Lie derivatives• Dynamics with constraints → Frobenius theorem on differential forms• Curvatures → Differential geometry

– Spacetime curvatures ~ General relativity

– Field space curvatures ~ Gauge theories

• Symmetries of quantum fields → Lie groups• Existence & uniqueness of problem → Topology

– Examples: Homology groups, Brouwer degree, Hurewicz homotopy groups, Morse theory, Atiyah-Singer index theorem, Gauss-Bonnet-Poincare theorem, Chern characteristic classes
