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 .
