In fractal space-time theory we built a superconducting model for generaliz
ed fields (electromagnetic and linear gravitation): generalized Maxwell and
London's equations, generalized Meissner and shielding effects, oscillatio
n modes in thin cylindrical gen eralized superconductors (generalized super
trons) and generalized superconductivity as a gauge theory. In such a conte
xt the atomic, planetary and double galaxies systems are self-organized as
fractal superconducting structures. The Cantorian E-(infinity) structure of
spacetime implies a two-dimensional cnoidal distribution of the particles
concentration for the solid-liquid interface and allows the evaluation of t
he kinetic moment of a neutron star. (C) 2001 Elsevier Science Ltd. All rig
