Speakers: Lucrezia Ravera (Politecnico di Torino)
I will discuss the role of spacetime torsion, in Einstein-Cartanformalism, as a natural, geometric way to couple gravity to matter.Then, I will present new geometries, in three spacetime dimensions,which involve a peculiar interplay between the vector and the singletirreducible components of the torsion which feature a formal analogywith the equation for a Beltrami fluid.
