Dynamical systems in quadratic teleparallel cosmology

RESUMO

We discuss the cosmological dynamics of general teleparallel quadratic gravity. Using a suitable set of variables, we write the cosmological field equations as a homogeneous dynamical system. We find that this system generically features projective fixed points, where the dynamics can be solved analytically, and exhibits finite time singularities as well as an asymptotically vanishing cosmological expansion.
