Weyl transformation and regular solutions in a deformed Jackiw-Teitelboim model

Understand

We revisit a deformed Jackiw-Teitelboim model with a hyperbolic dilaton potential, constructed in the preceding work [arXiv:1701.06340].

• Several solutions are discussed in a series of the subsequent papers, but all of them are pathological because of a naked singularity intrinsic to the deformation.
• In this paper, by employing a Weyl transformation to the original deformed model, we consider a Liouville-type potential with a cosmological constant term.
• Then regular solutions can be constructed with coupling to a conformal matter by using $SL(2)$ transformations.
