Nonlocal Lagrangian
text:
In field theory, a nonlocal Lagrangian is a Lagrangian, a type of functional L [ ϕ ] containing terms that are nonlocal in the fields ϕ , i.e. not polynomials or functions of the fields or their derivatives evaluated at a single point in the space of dynamical parameters. Examples of such nonlocal Lagrangians might be: L = 1 2 2 − 1 2 m 2 ϕ 2 + ϕ ∫ ϕ 2 d n y . L = − 1 4 F μ ν F μ ν . S = ∫ d t d d x [ ψ ∗ ψ − ℏ 2 2 m ∇ ψ ∗ ⋅ ∇ ψ ] − 1 2 ∫ d t d d x d d y V ψ ∗ ψ ψ ∗ ψ . The Wess–Zumino–Witten ac
