摘要: A local description of space and time in which translations are included the group gauge transformations is studied using formalism fibre bundles. It shown that flat Minkowski space–time may be obtained from a non-flat connection de Sitter structured bundle by choosing at least two different cross-sections. The interaction terms covariant derivative Dirac wave function correspond to interpreted as mass term equation, then cross-sections (gauges) fermion antifermion respectively.
