    ON the unification of physical fields
    (ALNEELAIN UNIVERSITY, 2008) ahmed hasan kathem meftah
    Abstract The most appropriate space for symmetry is the space of fiber bundle . The gauge group is symmetry group . The connection of fiber bundle represents the physical potential and the curvature manifests the field . It is for this reason that the theory of fiber bundles is extensively utilized in the study of gauge fields . In this research we consider the problem of unification of physical fields via the theory of fiber bundles . We treat gravitational field and the superimposed charges . We also treat the Euler — Lagrange equations in their global forms which are independent of coordinates . With the help of the bundle metric , the Euler — Lagrange equations of the unified field is obtained . Our main work and contribution concentrates on the interpretation of a charged particle as a geodesic in the fiber bundle where the projection is the usual path of the particle in Minkowski space . V
