The notion of four-momentum in TGD
... One key question concerns the classical and quantum counterparts of four-momentum. In TGD framework classical theory is an exact part of quantum theory. Classical four-momentum corresponds to Noether charge for preferred extremals of Kähler action. Quantal four-momentum in turn is assigned with the ...

... If Q ∈ V in then ∇F(Q) ∈ V in . Proof. Let ρ : V → V denote the action of the reflection z 7→ −z on V : then by definition V in = Fix(ρ) =: {Q ∈ V : ρQ = Q}. Differentiating F(Q) = F(ρQ) we have ∇F(Q) = ρ∇F(ρQ) = ρ∇F(Q) so ∇F(Q) ∈ Fix(ρ) = V in as claimed. Therefore any critical point of F|V in is a ...

Tutorial Note 7
... We often use the symbol “90°” to denote the congruence class represented by a right angle. Similarly, “180°” is used as a symbol which denotes the congruence class represented by the sum of two supplementary angles. It should be emphasized that we do not mean that there is a unit of measurement “°” ...

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.
