I. Cacciari,M. Del Gallo,S. Ippoliti,D. Lippi,T. Pietrosanti,W. Pietrosantis with models of deriving Yang-Mills and gravity in four dimensions from gravity formulated in higher dimensions, and commonly called Kaluza-Klein models. The different contributions by T. Kaluza and by O. Klein are carefully disentangled, in order to see the merits and the problems of this program.

J. J. Germida and their kinetic energy term in a Lagrangian are largely “dictated” by the local internal symmetry. It is shown how the Klein-Noether identities fix the action for any Yang-Mills theory (with mild conditions on the symmetry group). Field equations for higher-spin fields are mentioned. A further su

Yiu-Kwok Chan to physics. This of course is true also in ordinary shell-model calculations, in which usually only the low states are explicitly constructed, the others being hidden in the computer. In the shell-model case there is an implicit argument that, while the high states are not well treated, their effec

W. D. P. Stewart,P. Rowelllds (photon, intermediate bosons, gluons, etc.) come out on at least formally equal footings as gauge fields. At this stage there remains still an essential difference between them and the matter fields of leptons and quarks. The introduction of supersymmetry can help to eliminate this difference. B
