Classical String in Curved Backgrounds
Milovan Vasilic, Marko Vojinovic
The Mathisson-Papapetrou method is originally used for derivation of the particle world line equation from the covariant conservation of its stress-energy tensor. We generalize thi…
Covariant description of the black hole entropy in 3D gravity
M. Blagojevic, B. Cvetkovic
We study the entropy of the black hole with torsion using the covariant form of the partition function. The regularization of infinities appearing in the semiclassical calculation…
Black hole entropy from the boundary conformal structure in 3D gravity with torsion
M. Blagojevic, B. Cvetkovic
Asymptotic symmetry of the Euclidean 3D gravity with torsion is described by two independent Virasoro algebras with different central charges. Elements of this boundary conformal s…
Black hole entropy in 3D gravity with torsion
M. Blagojevic, B. Cvetkovic
The role of torsion in quantum three-dimensional gravity is investigated by studying the partition function of the Euclidean theory in Riemann-Cartan spacetime. The entropy of the…
