-deformation and Liouville gravity
Suguru Okumura, Kentaroh Yoshida
We consider a gravitational perturbation of the Jackiw-Teitelboim (JT) gravity with an arbitrary dilaton potential and study the condition under which the quadratic action can be s…
Gravitational perturbations as -deformations in 2D dilaton gravity systems
Takaaki Ishii, Suguru Okumura, Jun-ichi Sakamoto +1
We consider gravitational perturbations of 2D dilaton gravity systems and show that these can be recast into -deformations (at least) under certain conditions, where …
Weyl transformation and regular solutions in a deformed Jackiw-Teitelboim model
Suguru Okumura, Kentaroh Yoshida
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…
Comments on 2D dilaton gravity system with a hyperbolic dilaton potential
Hideki Kyono, Suguru Okumura, Kentaroh Yoshida
We proceed to study a (1+1)-dimensional dilaton gravity system with a hyperbolic dilaton potential. Introducing a couple of new variables leads to two copies of Liouville equations…
Deformations of the Almheiri-Polchinski model
Hideki Kyono, Suguru Okumura, Kentaroh Yoshida
We study deformations of the Almheiri-Polchinski (AP) model by employing the Yang-Baxter deformation technique. The general deformed AdS metric becomes a solution of a deformed…
