Cosmological perturbation theory in f(Q,T) gravity

We developed the cosmological linear theory of perturbations for f(Q, T) gravity, which is an extension of symmetric teleparallel gravity, with Q the non-metricity and T the trace of the stress-energy tensor. By considering an ansatz of f(Q, T) = f1(Q)+f2(T), which has been broadly studied in the li...
