Strings ending on branes from supergravity

Understand

We study geometries produced by brane intersections preserving eight supercharges.

• Typical examples of such configurations are given by fundamental strings ending on Dp branes and we construct gravity solutions describing such intersections.
• The geometry is specified in terms of two functions obeying coupled differential equations and the boundary conditions are determined by distributions of D branes.
• We show that a consistency of type IIB supergravity constrains the allowed positions of the branes.
