Primes

• Completeness
  • The five canonical varieties —

    This sourceDefinition of Banach spaces as complete normed vector spaces, establishing completeness as a foundational property for functional analysis.

• Fixed Point
  • Existence can be certified by structural conditions: a contractive map on a complete space has a unique attracting fixed point, and a continuous self-map of a convex compact set has at least one, so the existence of a resting state can be guaranteed before it is located.
• Metric
  • The fixed-point theorem for contractions — every contraction on a complete metric space has a unique fixed point — fires identically in numerical iteration, in dynamic-programming value iteration, in iterated-function-system image compression, and in proofs of economic-equilibrium existence.
