# invariance principles

## invariance principles:

see conservation lawsconservation laws,
in physics, basic laws that together determine which processes can or cannot occur in nature; each law maintains that the total value of the quantity governed by that law, e.g., mass or energy, remains unchanged during physical processes.

Another was the extension of the invariance principle to accelerating observers: the laws of nature themselves should be identical for all observers, regardless of the magnitude or direction of their acceleration.

They cover random systems with covariance inequalities, moment and maximal inequalities, the central limit theorem, the "almost sure" convergence, invariance principles, the law of the iterated logarithm, statistical applications, and integral functionals.
Dilworth does go on to point out that the principles do exist in explicit, refined forms, such as spatial and temporal invariance principles, conservation laws, and the law of inertia.
Similarly, conservation laws and symmetry laws are now grouped under various laws of invariance: "In fact, if the universal law of nature should be discovered, invariance principles would become merely mathematical transformations which leave the law invariant.

Invariance principles are one or more clauses establishing constant of motion in a general sense.
These clauses are written as conservation principles for the dynamic behavior and as invariance principles for the structure.
