An infinite dimensional generalization of an equation named after this man gives the time evolution of a probability measure in terms of a Euclidean inner product. For 10 points each:
[10h] Name this physicist. The Lie (“lee”) derivative of the symplectic structure along a vector field equals zero according to a result named after this physicist.
ANSWER: Joseph Liouville [accept Liouville’s theorem or Liouville equation or Liouville’s equation]
[10m] This operation appears in some versions of Liouville’s equation. This classical analogue of the commutator is denoted using curly brackets.
ANSWER: Poisson bracket
[10e] The Poisson bracket of canonical momentum and position is formally given by one of these functions named after Kronecker. These functions take their name from a Greek letter, and one of these functions named after Dirac nominally equals infinity at zero and equals zero everywhere else.
ANSWER: delta functions [accept Kronecker delta function or Dirac delta function or Dirac delta distribution]
