Horizon Quantization and Thermodynamics of the 2 + 1 Black Hole
We test on the 2+1 dimensional black hole the quantization method that we have previously proposed in four dimensions. While in the latter case the horizon dynamics is described, at the effective level, by the action of a relativistic membrane, in the 2+1 case it is described by a string. We show that this approach reproduces the correct value of the temperature and entropy of the 2+1 dimension...
متن کاملThe degree complexity of smooth surfaces of codimension 2
For a given term order, the degree complexity of a projective scheme is defined by the maximal degree of the reduced Gröbner basis of its defining saturated ideal in generic coordinates [2]. It is wellknown that the degree complexity with respect to the graded reverse lexicographic order is equal to the Castelnuovo-Mumford regularity [3]. However, much less is known if one uses the graded lexic...
متن کاملSlant surfaces of codimension two
A slant immersion is an isometric immersion from a Riemannian manifold into an almost Hermitian manifold with constant Wirtinger angle (1~ . In this article we study and characterize slant surfaces in the complex 2-plane ~2 via the Gauss map. We also prove that every surface without complex tangent points in a 4-dimensional almost Hermitian manifold M is slant with respect to a suitably chosen ...
متن کاملCodimension 2 Cycles on Products of Projective Homogeneous Surfaces
In the present paper, we provide general bounds for the torsion in the codimension 2 Chow groups of the products of projective homogeneous surfaces. In particular, we determine the torsion for the product of four Pfister quadric surfaces and the maximal torsion for the product of three Severi-Brauer surfaces. We also find an upper bound for the torsion of the product of three quadric surfaces w...
متن کاملViscous Cosmology and Thermodynamics of Apparent Horizon
It is shown that the differential form of Friedmann equations of FRW universe can be recast as a similar form of the first law ,TAdSA = dE + WdV , of thermodynamics at the apparent horizon of FRW universe filled with the viscous fluid. It is also shown that the generalized second law of thermodynamics holds at the apparent horizon of FRW universe and preserves dominant energy condition. PACS nu...
