Generating function (physics)

Generating function (physics)

Generating functions which arise in Hamiltonian mechanics are quite different from generating functions in mathematics. In the case of physics, generating functions act as a bridge between two sets of canonical variables when performing canonical transformation.

Details

There are four basic generating functions, summarized by the following table.

To confirm that this is the correct generating function, verify that it matches (2):::q = - frac{partial F_3}{partial p} = frac{-1}{Q} ,
