The path integral formulation is a description in quantum mechanics that generalizes the action principle of classical mechanics. It replaces the classical notion of a single, unique classical trajectory for a system with a sum, or functional integral , over an infinity of quantum-mechanically possible trajectories to compute a quantum amplitude. This formulation has proven crucial to the subsequent development of theoretical physics , because manifest Lorentz covariance time and space components of quantities enter equations in the same way is easier to achieve than in the operator formalism of canonical quantization. Unlike previous methods, the path integral allows one to easily change coordinates between very different canonical descriptions of the same quantum system. Another advantage is that it is in practice easier to guess the correct form of the Lagrangian of a theory, which naturally enters the path integrals for interactions of a certain type, these are coordinate space or Feynman path integrals , than the Hamiltonian. Possible downsides of the approach include that unitarity this is related to conservation of probability; the probabilities of all physically possible outcomes must add up to one of the S-matrix is obscure in the formulation.

Path integrals techniques are derived from a new definition [1] of Feynman path integrals. These techniques are used to establish that Feynman-Green functions for a given physical system are covariances of pseudomeasures suitable for its path integrals. The variance of a pseudomeasure is a more versatile tool than the Feynman-Green function it defines.

It is shown that a path integral expression of the generating functional is independent of the ordering scheme one employs. Thus one may choose any ordering scheme suitable for the problem under consideration even in the path integral formalism.

    Non-relativistic quantum mechanics is formulated here in a different way.
