( p, q )-five brane and ( p, q )-string solutions, their bound state and its near horizon limit

We determine (p, q)-string and (p, q)-five brane solutions of type iib supergravity using sl (2, ℤ)-symmetry of the full type iib superstring theory. we also determine sl (2, ℤ)-transformed solution corresponding to the bound state of ns5-branes and fundamental strings. then we analyze its near horizon limit and we show that it leads to the ads3 × s 3 with mixed fluxes.
