What was discovered

The BBGKY (Bogolyubov–Born–Green–Kirkwood–Yvon) hierarchy is a set of coupled equations describing the dynamics of a system of many interacting particles, where the equation for the s-particle distribution function involves the (s+1)-particle one. It is a central tool of statistical physics.

What it led to

  • Basis for deriving the Boltzmann equation from first principles
  • Closure methods in statistical physics and fluid dynamics
  • Applications in plasma physics and quantum statistical mechanics
