Axion-dilatonic conformal anomaly from AdS/CFT correspondence

Shin'ichi Nojiri; Sergei D. Odintsov; Sachiko Ogushi; Akio Sugamoto; Miho Yamamoto

the entropy (energy) is not proportional to the area (mass). The equation of motion of brane in BH background is presented as FRW equation. Using dual CFT description it is shown that dual field theory is not conformal one when
