摘要:

AbstractIt is shown that it is possible to describe the electron and the proton at rest within the framework of Dirac's relativistic theory of particles as electro‐magnetic stable, spheroidical particles like balloons with very thin envelopes. Their properties, especially their spins and their magnetic momenta, are exactly those, which have been measured at first and later on derived by Dirac. In this picture the neutron plays the rǒle of a system of two concentric and synchronically rotating balloons with a small distance between them at a positive energetic minimum of balance at 1.26 MeV. The magnetic moment of this particle has a negative sign and is of the correct si

摘要:

AbstractThe geometry of jet bundles is used for obtaining a geometric approach to time‐dependent Lagrangian systems, both in the regular and singular case. Generalized symmetries are introduced as being given by vector fields along the projection π1,0. This approach is shown to be very useful for giving a one‐to‐one correspondence between symmetries and constants of motion and allows a geometric version of the Second Noether Theorem. The theory is illustrated by several examples in which the gauge symmetries are explicitly
