Conformal gravity with totally antisymmetric torsion

نویسندگان

چکیده

We present a gauge theory of the conformal group in four spacetime dimensions with non-vanishing torsion. In particular, we allow for completely antisymmetric torsion, equivalent by Hodge duality to an axial vector whose presence does not spoil invariance theory, contrast claims antecedent literature. The requirement implies differential condition (in Killing equation) on aforementioned which leads Maxwell-like equation four-dimensional curved background. also give some preliminary results context $\mathcal{N}=1$ supergravity geometric approach, showing that if only constraint vanishing supertorsion all other constraints imposed approach are consequence closure Bianchi identities superspace. This paves way towards future complete investigation using (super)torsion.

Conformal dynamics of quantum gravity with torsion

The trace anomaly induced dynamics of the conformal factor is investigated in four-dimensional quantum gravity with torsion. The constraints for the coupling constants of torsion matter interaction are obtained in the infrared stable fixed point of the effective scalar theory. ⋆ On leave from Pedagogical Institute, 634041 Tomsk, Russia In a recent paper [1] the trace anomaly induced dynamics of...

On a Completely Antisymmetric Cartan Torsion Tensor

We discuss the general structure of metric geometries, and how metricity implies the complete antisymmetry of Cartan tensor; an application in the frame of Lie group theory is given. Interpretations of the completely antisymmetric torsion in physical models are reviewed.

A Note on Flat Metric Connections with Antisymmetric Torsion

In this short note we study flat metric connections with antisymmetric torsion T 6= 0. The result has been originally discovered by Cartan/Schouten in 1926 and we provide a new proof not depending on the classification of symmetric spaces. Any space of that type splits and the irreducible factors are compact simple Lie group or a special connection on S. The latter case is interesting from the ...
