A non-trivial connection for the metric-affine Gauss-Bonnet theory in
Bert Janssen, Alejandro Jimenez-Cano, Jose Alberto Orejuela
We study non-trivial (i.e. non-Levi-Civita) connections in metric-affine Lovelock theories. First we study the projective invariance of general Lovelock actions and show that all c…
(Non-)uniqueness of Einstein-Palatini Gravity
Bert Janssen, Alejandro Jimenez-Cano, Jose Alberto Orejuela +1
We analyse the most general connection allowed by Einstein-Hilbert theory in Palatini formalism. We also consider a matter lagrangian independent of the affine connection. We show…
Projective symmetries and induced electromagnetism in metric-affine gravity
Bert Janssen, Alejandro Jimenez-Cano
We present a framework in which the projective symmetry of the Einstein-Hilbert action in metric-affine gravity is used to induce an effective coupling between the Dirac lagrangian…
