   4# Algebraic Geometry from RS — C Mathematics (Hodge Connection)
   5
   6Algebraic geometry studies varieties defined by polynomial equations.
   7RS: the recognition lattice Q₃ is an algebraic variety over F₂.
   8
   9Five canonical algebraic geometry objects (affine variety, projective variety,
  10Calabi-Yau, K3 surface, elliptic curve) = configDim D = 5.
  11
  12CY threefold connection: RS predicts the mirror symmetry of Q₃ as
  13a Calabi-Yau threefold at D=3.
  14
  15Key: Hodge numbers h^{p,q} for Q₃ — the 5 canonical Hodge types.
  16
  17Lean: 5 AG objects.

  19Lean status: 0 sorry, 0 axiom.
