Invariant (physics) - Wikipedia
In theoretical physics, an invariant is an observable of a physical system which remains unchanged under some transformation. Invariance, as a broader term, also applies to the no change of form of physical laws under a transformation, and is closer in scope to the mathematical definition. Invariants of a system are deeply tied to the symmetries imposed by its env… See more
Informal usageIn the field of physics, the adjective covariant (as in covariance and contravariance of vectors) is often used informally as a synonym for "invariant". For example, the Schrödinger equation does not keep its written for… See more

5.2: Invariance of Physical Laws - Physics LibreTexts
The laws of physics include only those that satisfy this postulate. We will see that the definitions of energy and momentum must be altered to fit this postulate. Another outcome of this postulate is the famous equation \(E = mc^2\), which …
Principal Strains & Invariants - Continuum Mechanics
This page covers standard coordinate transformations, principal strains, and strain invariants. Everything here applies regardless of the type of strain tensor, so both \(\boldsymbol{\epsilon}\) and \({\bf E}\) will be used here.

10.5: Invariants - Physics LibreTexts
\(P\) and \(Q\) are a complete set of invariants for the electromagnetic field, meaning that the only other electromagnetic invariants are those that either can be determined from \(P\) and \(Q\) or depend on the derivatives of the fields, …
From classical physics it is known that invariance of a system under certain transformations is related to the conservation of corresponding quantities. The same ideas work also in quantum …
