Anti-de Sitter D-brane dynamics
We study the anti-de Sitter D-brane dynamics in Hamiltonian formulation. By exploiting the existence of certain conserved charges, we solve the equation of motion for a D1-brane in the AdS3 background and find the space-time dependent solutions. We further study the dynamics by mapping the problem to that of the open string tachyon, and examine the time dependent solutions in some detail.
متن کاملBrane Collisions in Anti-de Sitter Space
From the requirement of continuous matching of bulk metric around the point of brane collision we derive a conservation law for collisions of p-branes in (p+2)-dimensional space-time. This conservation law relates energy densities on the branes before and after the collision. Using this conservation law we are able to calculate the amount of matter produced in the collision of orbifoldfixed bra...
متن کاملTunneling between de Sitter and anti de Sitter black holes in a noncommutative D3-brane formalism
We obtain dS and AdS generalized Reissner-Nordstrom like black hole geometries in a curved D3-brane frame-work, underlying a noncommutative gauge theory on the brane-world. The noncommutative scaling limit is explored to investigate a possible tunneling of an AdS vacuum in string theory to dS vacuum in its low energy gravity theory. The Hagedorn transition is invoked into its self-dual gauge th...
متن کاملD5-brane in Anti-de Sitter Space and Penrose Limit
We consider the Penrose limit of the solution of D5-brane given in the Anti-de Sitter space and analyse the shape of the D5-brane in the pp-wave background. We find that the D5-brane leads to the branes and the throats connecting the branes. The branes spread on R with periodic values of the light-cone time x and the throats lie along x. We also give some comments on holography. May 2002 † seki...
متن کاملRemarks on Anti - De Sitter D - Branes
We present some preliminary investigations about the AdS 2 ×S 2 D3-branes in AdS 3 ×S 3. We analyse the quadratic fluctuations of Dirac–Born–Infeld action around a given semi-classical D-brane configuration and compare them with results obtained by using conformal-field-theory techniques. We finally study classical motions of open strings attached to those D-branes and analyse the rôle of the s...
