Spinors and torsion in general relativity
Journal Article
·
· Found. Phys.; (United States)
Conformal rescalings of spinors are considered, in which the factor ..cap omega.., in epsilon/sub AB/..--> cap omega..epsilon/sub AB/, is allowed to be complex. It is argued that such rescalings naturally lead to the presence of torsion in the space-time derivative del/sub a/. It is further shown that, in standard general relativity, a circularly polarized gravitational wave produces a (nonlocal) rotation effect along rays intersecting it similar to, and apparently consistent with, the local torsion of the Einstein-Cartan-Sciama-Kibble theory. The results of these deliberations are suggestive rather than conclusive.
