Classical Stability of Black Branes ∗
نویسنده
چکیده
Classical stability behaviors of various static black brane backgrounds under small perturbations have been summarized briefly. They include cases of black strings in AdS5 space, charged black p-brane solutions in the type II supergravity, and the BTZ black string in four-dimensions. The relationship between dynamical stability and local thermodynamic stability the so-called Gubser-Mitra conjecture has also been checked for those cases.

Classical and Thermodynamic Stability of Black Branes
It is argued that many non-extremal black branes exhibit a classical Gregory-Laflamme instability if, and only if, they are locally thermodynamically unstable. For some black branes, the Gregory-Laflamme instability must therefore disappear near extremality. For the black p-branes of the type II supergravity theories, the Gregory-Laflamme instability disappears near extremality for p = 1, 2, 4 ...
متن کاملClassical Stability of Charged Black Branes and the Gubser-Mitra Conjecture
We have investigated the classical stability of magnetically charged black p-brane solutions for string theories that include the case studied by Gregory and Laflamme. It turns out that the stability behaves very differently depending on a coupling parameter between dilaton and gauge fields. In the case of Gregory and Laflamme, it has been known that the black brane instability decreases monoto...
متن کاملInstabilities of Near-Extremal Smeared Branes and the Correlated Stability Conjecture
We consider the classical and local thermodynamic stability of nonand near-extremal Dp-branes smeared on a transverse direction. These two types of stability are connected through the correlated stability conjecture for which we give a proof in this specific class of branes. The proof is analogous to that of Reall for unsmeared branes, and includes the construction of an appropriate two-paramet...
متن کاملBlack Objects in the Gauge Theory of P - Branes
Within the context of the recently formulated classical gauge theory of rel-ativistic p-branes minimally coupled to general relativity in D-dimensional spacetimes, we obtain solutions of the field equations which describe black objects. Explicit solutions are found for two cases: D > p + 1 (true p-branes) and D = p + 1 (p-bags).
متن کاملOrigin of black string instability
It is argued that many nonextremal black branes exhibit a classical Gregory-Laflamme (GL) instability. Why does the universal instability exist? To find an answer to this question and explore other possible instabilities, we study stability of black strings for all possible types of gravitational perturbation. The perturbations are classified into tensor-, vector-, and scalar-types, according t...
