Dirac bracket — The Dirac bracket is a generalization of the Poisson bracket developed by Paul Dirac to correctly treat systems with second class constraints in Hamiltonian mechanics and canonical quantization. It is an important part of Dirac s development of… … Wikipedia
Kronecker delta — In mathematics, the Kronecker delta or Kronecker s delta, named after Leopold Kronecker (1823 1891), is a function of two variables, usually integers, which is 1 if they are equal, and 0 otherwise. So, for example, delta {12} = 0, but delta {33} … Wikipedia
