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.)

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.

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).

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]?

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.

Invariant physical fields with gauge freedom
Physica A: Statistical Mechanics and its Applications, 1982Abstract In the context of gauge theories, a field is made invariant to some space-time transformations if it is gauge-equivalent to its image. This note provides examples of both gauge and matter fields which obey such an invariant condition. The gauge group will be SU(2) and isotriplets of scalars and isodoublets of Dirac fields will be considered ...
