Generalized 2D dilaton gravity and KGB
Published 20 Dec 2018 in gr-qc and hep-th | (1812.08847v2)
Abstract: We show explicitly that the nonminimal coupling between the scalar field and the Ricci scalar in 2D dilaton gravity can be recast in the form of kinetic gravity braiding (KGB). This is as it should be, because KGB is the 2D version of the Horndeski theory. We also determine all the static solutions with a linearly time-dependent scalar configuration in the shift-symmetric KGB theories in 2D.
