What was discovered

Secondary characteristic classes defined by Shiing-Shen Chern and Jim Simons in their 1974 paper 'Characteristic Forms and Geometric Invariants', which gave rise to Chern–Simons theory.

What it led to

  • Chern–Simons topological quantum field theory
  • advances in condensed matter physics (quantum Hall effect)
  • topological invariants in knot theory
  • connections between differential geometry and theoretical physics
