Hamiltonian perturbation theory in f(R) gravity
Tuomas Multamäki, Jaakko Vainio, Iiro Vilja
Hamiltonian perturbation theory is used to analyse the stability of f(R) models. The Hamiltonian equations for the metric and its momentum conjugate are written for f(R) Lagrangian…

Maximal symmetry and metric-affine f(R) gravity
Tuomas Multamäki, Jaakko Vainio, Iiro Vilja
The affine connection in a space-time with a maximally symmetric spatial subspace is derived using the properties of maximally symmetric tensors. The number of degrees of freedom i…
