recurrence, measurability, determinacy and decidability

NOTICE
  • DO NOT TRUST THE FOLLOWING
OBSERVATIONS
  • numerical integration: some computation would never halt
  • someone guesses approximate fixed point of above computation
  • what is the "probability" whether the guesser is right
  • as far as the system is integrable, this would make sense
  • automata: cyclic group could be represented as circular state machine
  • apply homology to nodes of an automaton: nodes are loops
  • John von Neumann: he worked on cellular automata after his (mathematical) effort on ergodic theory and operator ring theory
  • John Nash: existence of core of game / Riemannian embedding
  • William Thurston: geometrization conjecture and following studies of automata
SPECULATION
  • there must be an inclusive viewpoint for understanding them all as one:
  • ergodic theory
  • probability theory (especially, stochastic process)
  • metamathematics, set-theoretic and lattice-theoretic
  • model theory
  • (non-relativistic) quantum field theory
  • general relativity
  • automata theory
  • thermodynamics
  • dynamic macroeconomics
  • financial and monetary economics
TURBULENCE/RANDOMNESS/NON-INTEGRABILITY
  • what is "mean coordinates" of chaotic orbit?
