Gravitational and electroweak unification by replacing diffeomorphisms with larger group
The covariance group for general relativity, the diffeomorphisms, is replaced
by a group of coordinate transformations which contains the diffeomorphisms as
a proper subgroup. The larger group is defined by the assumption that all
observers will agree whether any given quantity is conserved. Alternatively,
and equivalently, it is defined by the assumption that all observers will agree
that the general relativistic wave equation describes the propagation of light.
Thus, the group replacement is analogous to the replacement of the Lorentz
group by the diffeomorphisms that led Einstein from special relativity to
general relativity, and is also consistent with the assumption of constant
light velocity that led him to special relativity. The enlarged covariance
group leads to a non-commutative geometry based not on a manifold, but on a
nonlocal space in which paths, rather than points, are the most primitive
invariant entities. This yields a theory which unifies the gravitational and
electroweak interactions. The theory contains no adjustable parameters, such as
those that are chosen arbitrarily in the standard model.Comment: 28 pages
Unified Field Theory From Enlarged Transformation Group. The Covariant Derivative for Conservative Coordinate Transformations and Local Frame Transformations
Pandres has developed a theory in which the geometrical structure of a real
four-dimensional space-time is expressed by a real orthonormal tetrad, and the
group of diffeomorphisms is replaced by a larger group called the conservation
group. This paper extends the geometrical foundation for Pandres' theory by
developing an appropriate covariant derivative which is covariant under all
local Lorentz (frame) transformations, including complex Lorentz
transformations, as well as conservative transformations. After defining this
extended covariant derivative, an appropriate Lagrangian and its resulting
field equations are derived. As in Pandres' theory, these field equations
result in a stress-energy tensor that has terms which may automatically
represent the electroweak field. Finally, the theory is extended to include
2-spinors and 4-spinors.Comment: Aug 25 replacement has corrected margin width
