Abstract
|
In this paper we find the fully gauge invariant cosmological perturbation equations in braneworld teleparallel gravity. In this theory, perturbations are the result of small fluctuations in the pentad field. We derive the gauge invariant ’potentials’ for both geometric and matter variables. In teleparallel gravity, pentad perturbations can only contain scalar and vector modes. This is in contrast to the metric fluctuations in general relativity.
