Twisted sectors in three-dimensional gravity
نویسنده
چکیده
Twisted sectors –solutions to the equations of motion with nontrivial monodromies– of three dimensional Euclidean gravity are studied. We argue that upon quantization this new sector of the theory provides the necessary (and no more) degrees of freedom to account for the Bekenstein-Hawking entropy of three-dimensional black holes. PACS: 04.70.Dy; 04.60.Kz

Multi-Objective Optimization of Tio2-Water Nanofluid Flow in Tubes Fitted With Multiple Twisted Tape Inserts in Different Arrangement
In this paper, experimentally derived correlations of heat transfer and pressure drop are used in a Pareto based Multi-Objective Optimization (MOO) approach to find the best possible combinations of heat transfer and pressure drop of TiO2-water nanofluid flow in tubes fitted with multiple twisted tape inserts in different arrangement. In this study there are four independent design variables: t...
متن کاملSectors of solutions in Three-dimensional Gravity and Black Holes
We examine the connection between three dimensional gravity with negative cosmological constant and two-dimensional CFT via the Chern-Simons formulation. A set of generalized spectral flow transformations are shown to yield new sectors of solutions. One implication is that the microscopic calculation of the entropy of the Bañados-Teitelboim-Zanelli (BTZ) black hole is corrected by a multiplicat...

This is the second in a series of papers which consider the orbifolds of permutation-type as candidates for new physical string systems at higher central charge. In the first paper, I worked out the extended actions of the twisted sectors of those orbifolds – which exhibit new permutation-twisted world-sheet gravities and correspondingly extended diffeomorphism groups. In this paper I begin the...
متن کاملMaxwell gravity
The complete on-shell action of topological Einstein-Maxwell gravity in four-dimensions is presented. It is shown explicitly how this theory for SU(2) holonomy manifolds arises from four-dimensional Euclidean N = 2 supergravity. The twisted local BRST symmetries and twisted local Lorentz symmetries are given and the action and stress tensor are shown to be BRST-exact. A set of BRST-invariant to...
متن کاملTwisted World-Sheet Gravities
This is the first in a series of papers in which I investigate the orbifolds of permutation-type as candidates for new physical string systems at multiples of critical closed-string central charges. Examples include the bosonic orientation orbifolds, the bosonic permutation orbifolds and others, as well as superstring extensions. In this paper I use the extended (twisted) Virasoro algebras of t...
