제목: Extremal Black Holes and Holographic C-theorem
(reference : arXiv : 1208.4509 [hep-th])

연사: Prof. Jong-Dae Park (Kyung Hee U.)

일시: 2012. 11. 28(수) 4pm

장소: To be announced

초록: We found Bogomol'nyi type of first order differential equations
in three dimensional Einstein gravity and effective second order
ones in new massive gravity when an  interacting scalar field is
minimally coupled. Using these equations in Einstein gravity, we
obtain analytic solutions corresponding to extremally rotating
hairy black holes. We also obtain perturbatively  extremal black hole
solutions in new massive gravity using these lower order differential equations.
All these solutions have the anti de-Sitter spaces as their asymptotic geometries and as the
near horizon ones. This feature of solutions interpolating two
anti de-Sitter spaces leads to the construction of holographic
c-theorem in these cases. Since our lower order equations reduce
naturally to the well-known equations for domain walls, our
results can be regarded as the natural extension of domain walls
to more generic cases.
