Obtaining consistent Lorentz gauging for a gravitationally coupled fermion
John Fredsted
For internal gauge forces, the result of locally gauging, i.e., of performing the substitution , is physically the same whether performed on the action or o…
Spinors and gravity without Lorentz indices
John Fredsted
Coupling spinor fields to the gravitational field, in the setting of general relativity, is standardly done via the introduction of a vierbein field and the (associated minimal) sp…
Electroweak interaction without projection operators using complexified octonions
John Fredsted
Using complexified octonions, a formalism seemingly capable of describing the coupling of spinors to the electroweak force without projection operators is presented.
Spinor fields without Lorentz frames in curved spacetime using complexified quaternions
John Fredsted
Using complexified quaternions, a formalism without Lorentz frames, and therefore also without vierbeins, for dealing with tensor and spinor fields in curved spacetime is presented…
Linking electroweak and gravitational generators
John Fredsted
Using complexified quaternions, an intriguing link between generators of two different and surprisingly commuting four-dimensional representations of the SU(2)xU(1) Lie group, and…
Natural octonionic generalization of general relativity
John Fredsted
An intriguingly natural generalization, using complex octonions, of general relativity is pointed out. The starting point is the vierbein-based double dual formulation of the Einst…
