Cancellation of UV divergences in ghost-free infinite derivative gravity
Alexey S. Koshelev, Oleg Melichev, Leslaw Rachwal
We consider the most general covariant gravity action up to terms that are quadratic in curvature. These can be endowed with generic form factors, which are functions of the d'Alem…

Quadratic gravity with propagating torsion and asymptotic freedom
Oleg Melichev
We consider a class of metric-affine gravitational theories with action quadratic in curvature and torsion tensors. Using the heat kernel technique, we compute the torsion contribu…
