摘要: A new model of DBI inflation is introduced where the mobile brane, inflaton field, moving relativistically inside a Lifshitz throat with an arbitrary anisotropic scaling exponent z. After dimensional reduction to four dimension general covariance broken explicitly both in matter and gravitational sectors. The action for metric field perturbations are obtained it shown be similar classifications made effective theory literature.
