Coincident (Super)–Dp–Branes of Codimension One

چکیده
We consider properties of a covariant worldvolume action for a system of N coincident Dp– branes in D=(p+2) dimensional space–time (so called codimension one branes). In the case of N coincident D0–branes in D=2 we then find a generalization of this action to a model which includes fermionic degrees of freedom and is invariant under target–space supersymmetry and worldline kappa–symmetry. We find that the type IIA D = 2 superalgebra generating the supersymmetry transformations of the ND0–brane system acquires a non–trivial “central extension” due to a nonlinear contribution of U(N) adjoint scalar fields. Peculiarities of space–time symmetries of coincident Dp–branes are discussed.

Noncommutative and Ordinary Super Yang-Mills on (D(p− 2), Dp) Bound States
We study properties of (D(p− 2), Dp) nonthreshold bound states (2 ≤ p ≤ 6) in the dual gravity description. These bound states can be viewed as Dp-branes with a nonzero NS B field of rank two. We find that in the decoupling limit, the thermodynamics of the Np coincident Dp-branes with B field is the same not only as that of Np coincident Dp-branes without B field, but also as that of the Np−2 c...
متن کاملRemarks on non-BPS D-branes
Following Sen’s discovery of various stable non-BPS D-branes, K-theory has been shown to be the appropriate mathematical framework for classifying conserved D-brane charges. The classification accounts for known D-branes and predicts some new ones including a D8-brane in type I superstring theory. After briefly reviewing these developments, we discuss certain issues pertaining to the D8brane, w...
متن کاملSuperembedding approach to superstring in AdS 5 × S 5 superspace
We review the spinor moving frame formulations and generalized action principle for super-p-branes, describe in detail the superembedding approach to superstring in general type IIB supergravity background and present the complete superembedding description of type IIB superstring in the AdS5 × S 5 superspace. This contribution is devoted to the memory of Wolfgang Kummer who untimely left us in...
متن کاملNoncommutative Solitons and Intersecting D-Branes
Brane configurations that contain a tachyonic mode are unstable and will decay. The decay modes vary depending on the unstable D-brane configurations involved ~see the reviews @1–3#!. In bosonic string theory, all D-branes are unstable. The tachyon on the brane may condense to solitonic solutions of the open string tachyon field theory. These solitons have been noted to correspond to lower dime...
متن کاملNoncommutative Multi-instantons on R ×s 2
Generalizing self-duality on R2×S2 to higher dimensions, we consider the Donaldson-UhlenbeckYau equations on R2n×S2 and their noncommutative deformation for the gauge group U(2). Imposing SO(3) invariance (up to gauge transformations) reduces these equations to vortex-type equations for an abelian gauge field and a complex scalar on R θ . For a special S-radius R depending on the noncommutativi...
