Black Hole Entropy in M - Theory
Extremal black holes in M-theory compactification on M × S are microscopically represented by fivebranes wrapping P × S, where M is a Calabi-Yau threefold and P is a four-cycle in M . Additional spacetime charges arise from momentum around the S and expectation values for the self-dual three-form field strength in the fivebrane. The microscopic entropy of the fivebrane as a function of all the ...
متن کاملOrganizational Black Hole Theory
There are issues in organizations that require new theoretical formulation. Hence, metaphorical theorizing is used in the study of organizations to interpret them and understand their complexities. In this method, the organization is likened to an entity and one of the key features of that entity is generalized to the organization. It should be borne in mind that most organizational theories ar...
متن کاملBlack Hole Entropy and String Theory
This is an expanded version of a talk given at “IInd Recontre du Vietnam” held at Ho Chi Minh City in October, 1995. We discuss several aspects of black hole entropy in string theory. We first explain why the geometric entropy in two dimensional noncritical string theory is nonperturbatively finite. We then explain the philosophy of regarding massive string states as black branes and how the Be...
متن کاملFinite black hole entropy and string theory.
An accelerating observer sees a thermal bath of radiation at the Hawking temperature which is proportional to the acceleration. Also, in string theory there is a Hagedorn temperature beyond which one cannot go without an infinite amount of energy. Several authors have shown that in the context of Hawking radiation a limiting temperature for string theory leads to a limiting acceleration, which ...
متن کاملBlack hole entropy from classical Liouville theory
In this article we compute the black hole entropy by finding a classical central charge of the Virasoro algebra of a Liouville theory using the Cardy formula. This is done by performing a dimensional reduction of the Einstein Hilbert action with the ansatz of spherical symmetry and writing the metric in conformally flat form. We obtain two coupled field equations. Using the near horizon approxi...
