Colliding waves in metric-affine gravity
Alberto García, Claus Lämmerzahl, Alfredo Macías +2
We generalize the formulation of the colliding gravitational waves to metric-affine theories and present an example of such kind of exact solutions. The plane waves are equipped wi…

Supersymmetric quantum cosmology for Bianchi class A models
Alfredo Macías, Eckehard W. Mielke, José Socorro
The canonical theory of (N=1) supergravity, with a matrix representation for the gravitino covector-spinor, is applied to the Bianchi class A spatially homogeneous cosmologies. The…
