“…This is equivalent to the analysis performed in [4] where this kind of Sp-branes was named as S − p-brane 2 . Then we apply this general procedure in section-5 to 1 S-brane action was also studied in [16,17,18,19]. 2 It is necessary to mention one important subtlety considering our results and the work [4].…”

We study aspects of Dirichlet S-branes, which are defined as Dirichlet boundary condition on a time like embedding of open strings, in general backgrounds. By applying T -duality along an isometry of the unphysical dS 2 -branes in NS-NS supported AdS 3 -background, we find S0-brane. We also study the time dependent tachyon condensation on the unstable Dp-brane and interpret the singular solutions as lower dimensional S(p-1)-brane that couples to real Ramond-Ramond fields while to imaginary NS-NS modes.

“…It has been argued that these corrections are all zero for a BPS object, however we suspect that this is only true for flat space configurations where the requirement of minimal energy is satisfied by an object being BPS. However the presence of an electric field on the brane world-volumes reduces the velocity of the collapse by the factor √ 1 − e 2 and thus the leading order Lagrangian may remain valid -although there are difficulties associated with near critical electric fields and the DBI [13]. In curved space the gravitational red shift appears to reduce the velocity of the fuzzy sphere to sub-luminal speeds, however there was found to be no turning point solution in the static potential and therefore no formation of non-Abelian bound states (with the exception of D0-branes in the D6-brane background.…”

We use the non-Abelian DBI action to study the dynamics of N coincident Dp-branes in an arbitrary curved background, with the presence of a homogenous world-volume electric field. The solutions are natural extensions of those without electric fields, and imply that the spheres will collapse toward zero size. We then go on to consider the D1 − D3 intersection in a curved background and find various dualities and automorphisms of the general equations of motion. It is possible to map the dynamical equation of motion to the static one via Wick rotation, however the additional spatial dependence of the metric prevents this mapping from being invertible. Instead we find that a double Wick rotation leaves the static equation invariant. This is very different from the behaviour in Minkowski space. We go on to construct the most general static fuzzy funnel solutions for an arbitrary metric either by solving the static equations of motion, or by finding configurations which minimise the energy. As a consistency check we construct the Abelian D3-brane world-volume theory in the same generic background and find solutions consistent with energy minimisation. In the N S5-brane background we find time dependent solutions to the equations of motion, representing a time dependent fuzzy funnel. These solutions match those obtained from the D-string picture to leading order suggesting that the action in the large N limit does not need corrections. We conclude by generalising our solutions to higher dimensional fuzzy funnels.

“…Heuristically, a field of this strength would break the string apart. However, overcritical fields probably do make sense physically as a mechanism for D-brane decay [6,7,8]. Nowadays, there are many methods available to obtain Schwinger's formulas (1.1), (1.2).…”
