The Biot-Savart operator and electrodynamics on
... We study the generalization of the Biot-Savart law from electrodynamics in the presence of curvature. We define the integral operator BS acting on all vector fields on subdomains of the threedimensional sphere, the set of points in R4 that are one unit away from the origin. By doing so, we establish ...

The Path Integral Approach to Quantum Mechanics
... more flexible than the standard operator - state description, but I do not intend to get into an argument about this. Objectively, the strongest points in favour of the path integral appoach are that • unlike the usual Hamiltonian approach the path integral approach provides a manifestly Lorentz cov ...

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.
