Two-dimensional (bi-)scalar gravities from four-dimensional Horndeski
M. Shams Nejati, M. H. Vahidinia
We develop a classical two-dimensional bi-scalar gravity based on the Kaluza-Klein reduction applied to the four-dimensional Horndeski theory. One of the scalar fields arises from…

Jackiw-Teitelboim Gravity Generates Horndeski via Disformal Transformations
M. Shams Nejati, M. H. Vahidinia
We show that the most general two-dimensional dilaton gravity theory with second-order field equations, which includes Horndeski and Kinetic Gravity Braiding families, may be obtai…
