Curved branes from string dualities

We describe a simple method for generating new string solutions for which the brane worldvolume is a curved space. As a starting point we use solutions with NS-NS charges combined with two-dimensional CFTs representing different parts of spacetime. We illustrate our method with many examples, some o...

In particular, we discuss the case of a D5-brane wrapped on AdS 3 × S 3, a solution interpolating between AdS 3 × S 3 × ℝ 5 and AdS 3 × S 3 × S 3 × ℝ, and a D3-brane wrapped over S 3 × ℝ or AdS 2 × S 2.
