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.

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.

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.

Invariant Tensor Fields in Physics and the Classical Groups
SIAM Journal on Applied Mathematics, 1971The relativistic S-matrix with spin transforms as an invariant tensor under the action of the homogeneous Lorentz group. This transformation property enables one to analyze the structure of the S-matrix from the viewpoint of group theory. Here this procedure is generalized and applied to tensor fields which are invariant under one of the classical ...

The logical foundations of invariance principles in physics - I
Il Nuovo Cimento, 1959The logical foundations of invariance principles in physics are discussed with the aim of clarifying the physical meaning of the main concepts and operations involved. Care is taken to avoid the use of coordinate systems, which are likely to lead to misunderstandings in the most critical points.
