Conformal Invariance in Physics
Reviews of Modern Physics, 1962The conformal covariance of certain basic equations of modern physics is shown. This covariance is valid generally only when the requirement of constant rest masses is relaxed. It is necessary that all rest masses transform in a conformally covariant way. (L.T.W.)

Invariance in elementary particle physics
Reports on Progress in Physics, 1959An account, as non-technical as possible, is given of the invariance properties that have important applications in elementary particle physics. These can be classified in several ways. Firstly some are related to continuous groups (rotations), others to discrete groups (inversions).

1995
The world is very complicated and it is clearly impossible for the human mind to understand it completely. Man has therefore devised an artifice which permits the complicated nature of the world to be blamed on something which is called accidental and thus permits him to abstract a domain in which simple laws can be found.

Physics-like invariants for vision
Proceedings of the Workshop on Physics-Based Modeling in Computer Vision, 2002Unlike geometric invariants, the invariants described here concern the physical processes that form images, involving shading, IR, radar, sonar, etc. The image formed by such a process depends on many variables in addition to the geometry, such as the characteristics of the lighting or other incident radiation, the imaging system, etc.

Conformal Invariance in Physics
1976In the last decade mathematical physicists have been especially interested by the group of conformal transformations of space-time — the so-called conformal group. What are the main physical reasons for the increasing interest in such an old subject [1]?

On the physical implications of gauge invariance
Il Nuovo Cimento A, 1966Gauge invariance of the equations of motion is analysed along the pattern of Noether's theorem and the physical implications of this invariance property are derived. They are not so strong as usually stated.

Invariance Principles of Nuclear Physics
Annual Review of Nuclear Science, 1958Space inversion (P), time reversal (T), and chargeconjugation (C) are discussed. Some mixed operations obtained by combining P, C, and T are described. A discussion of isotopic spin invariance or charge independence and other related operations is presented.

The Lorentz invariance of physical theories
1973In the previous chapters considerable stress has been laid on the description of physical processes in a Lorentz invariant manner. This result was achieved by the use of the four-vector, whose scalar product with itself or other four-vectors formed a Lorentz invariant quantity.
