THE QUANTIZATION OF THE SPACE-TIME DEFECTS IN THE EARLY UNIVERSE

In Riemann-Cartan manifold U-4, a new topological invariant is obtaine d by means of the torsion tenser. In order to describe the space-time defects (which appear in the early universe due to torsion) in an inva riant form, the new topological invariant is introduced to measure the size of defects and it is interpreted as the dislocation flux in inte rnal space. Using the so-called phi-mapping method and the gauge poten tial decomposition, the dislocation flux is quantized in units of the Planck length. The quantum numbers are determined by the Hopf indices and the Brouwer degrees. Furthermore, the dynamic form of the dislocat ions is also studied by defining an identically conserved current.
