Remarks 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...
متن کاملAnti-de Sitter D-branes in Curved Backgrounds
We investigate the properties of the AdS D1-branes which are the bound states of a curved D1-brane with n fundamental strings (F1) in the AdS3 spacetime, and the AdS D2-branes which are the axially symmetric bound states of a curved D2-brane with m D0-branes and n fundamental strings in the AdS3 × S spacetime. We see that, while the AdS D1-branes asymptotically approach to the event horizon of ...
متن کاملBranes in Anti De Sitter Space–time. *
An intense study of the relationship between certain quantum theories of gravity realized on curved backgrounds and suitable gauge theories, has been originated by a remarkable conjecture put forward by Maldacena almost one year ago. Among the possible curved vacua of superstring or M–theory, spaces having the form of an Anti– de Sitter space–time times a compact Einstein manifold, have been pl...
متن کاملBranes in the bulk of Anti-de Sitter space
We consider (3 + 1)-dimensional N = 4 super Yang-Mills theory with a nonvanishing scalar Higgs vacuum expectation value, and compare this theory to AdS supergravity with branes in the bulk. We show that the one-loop effective potential for excitations of the Yang-Mills field agrees with the classical linearized potential for brane waves in the AdS picture in the limit of long wavelengths. This ...
متن کاملAnti-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.
