Massless string theory black holes as black diholes and quadruholes.
Massless black holes can be understood as bound states of a (positive-mass) extreme a p 3 black hole and a singular object with opposite (i.e., negative) mass with vanishing Arnowitt-Deser-Misner (total) mass but nonvanishing gravitational field. Supersymmetric balance of forces is crucial for the existence of this kind of bound states and explains why the system does not move at the speed of...
متن کاملBlack-hole-wave duality in string theory.
Extreme 4-dimensional dilaton black holes embedded into 10-dimensional geometry are shown to be dual to the gravitational waves in string theory. The corresponding gravitational waves are the generalization of pp-fronted waves, called supersymmetric string waves. They are given by Brinkmann metric and the twoform field, without a dilaton. The non-diagonal part of the metric of the dual partner ...
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 کاملMassless Black Holes and Conifolds in String Theory
Low-energy effective field theories arising from Calabi-Yau string compactifications are generically inconsistent or ill-defined at the classical level because of conifold singularities in the moduli space. It is shown, given a plausible assumption on the degeneracies of black hole states, that for type II theories this inconsistency can be cured by nonperturbative quantum effects: the singular...
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...
