چکیده
In this paper, we investigate the influence of angular momentum a charged particle around non-extremal and extremal Einstein-Maxwell-Dilaton-Axion black holes on Lyapunov exponent. The momentum's ranges spatial regions where bound exponent is violated are found for certain values rotation parameter dilatonic constant holes. This violation always exists when large enough directions opposite to those outside extermal hole relatively large. near-horizon holes, depends particle, does not depend value momentum.

Axion-dilaton Black Holes.
In this talk some essential features of stringy black holes are described. We consider charged four-dimensional axion-dilaton black holes. The Hawking temperature and the entropy of all solutions are shown to be simple functions of the squares of supercharges, defining the positivity bounds. Spherically symmetric and multi black hole solutions are presented. The extreme solutions have some unbr...
متن کاملOn uniqueness of static Einstein-Maxwell-dilaton black holes
We prove uniqueness of static, asymptotically flat spacetimes with nondegenerate black holes for three special cases of Einstein-Maxwell-dilaton theory: For the coupling “α = 1” (which is the low energy limit of string theory) on the one hand, and for vanishing magnetic or vanishing electric field (but arbitrary coupling) on the other hand. Our work generalizes in a natural, but non-trivial way...
متن کاملHolographic dual of linear dilaton black hole in Einstein-Maxwell-dilaton-axion gravity
Motivated by the recently proposed Kerr/CFT correspondence, we investigate the holographic dual of the extremal and non-extremal rotating linear dilaton black hole in Einstein-Maxwell-Dilaton-Axion Gravity. For the case of extremal black hole, by imposing the appropriate boundary condition at spatial infinity of the near horizon extremal geometry, the Virasoro algebra of conserved charges assoc...
متن کاملCharge quantization of axion-dilaton black holes.
We present axion-dilaton black-hole and multi-black-hole solutions of the low-energy string effective action. Under SL(2, R) electric-magnetic duality rotations only the "hair" (charges and asymptotic values of the fields) of our solutions is transformed. The functional form of the solutions is duality invariant. Axion-dilaton black holes with zero entropy and zero area of the horizon form a fa...
متن کاملKramer-Neugebauer transformation for Einstein-Maxwell-dilaton-axion theory.
The Kramer–Neugebauer–like transformation is constructed for the stationary axisymmetric D=4 Einstein–Maxwell–dilaton–axion system. This transformation directly maps the dualized sigma–model equations of the theory into the nondualized ones. Also the new chiral 4× 4 matrix representation of the problem is presented.
