THE CONCEPTUAL BASIS OF QUANTUM FIELD THEORY
... A field is here taken to mean a physical variable that is a function of space-time coordinates x = (x, t). In order for our theories to be in accordance with special relativity, we will have to specify how a field transforms under a homogeneous Lorentz transformation, x0 = Lx . ...

Axioms of Relativistic Quantum Field Theory
... Now, trying to solve the original partial differential equation leads to a division problem for distributions. Of course, the multiplication of a polynomial P = P(p) and a distribution T ∈ S given by PT (u) := T (Pu) is well-defined because Pu(p) = P(p)u(p) is a function Pu ∈ S for each u ∈ S . So ...

... sometimes write PEF for this projector. The Kubo formula for the AC conductivity at temperature T > 0 and frequency ν > 0 is derived in linear response theory [8] (see also [3, 27]) by considering a time-dependent Hamiltonian with an external electric field at frequency ν > 0. This Hamiltonian can b ...

Now consider just any coordinate frame, that is, the original coordinates (t, x, y, z) are completely arbitrary, in general mutually independent, differentiable functions of four quantities u = {uµ , µ = 0, · · · , 3} . Being differentiable here means that every point is surrounded by a small region ...

Noether's theorem
Noether's (first) theorem states that every differentiable symmetry of the action of a physical system has a corresponding conservation law. The theorem was proven by German mathematician Emmy Noether in 1915 and published in 1918. The action of a physical system is the integral over time of a Lagrangian function (which may or may not be an integral over space of a Lagrangian density function), from which the system's behavior can be determined by the principle of least action.Noether's theorem has become a fundamental tool of modern theoretical physics and the calculus of variations. A generalization of the seminal formulations on constants of motion in Lagrangian and Hamiltonian mechanics (developed in 1788 and 1833, respectively), it does not apply to systems that cannot be modeled with a Lagrangian alone (e.g. systems with a Rayleigh dissipation function). In particular, dissipative systems with continuous symmetries need not have a corresponding conservation law.
