" "It is shown that many of the s of type II string theory and d = 11 supergravity can have boundaries on other p-branes. The rules for when this can and cannot occur are derived from charge conservation. For example it is found that membranes in d = 11 supergravity and IIA string theory can have boundaries on s. The boundary dynamics are governed by the self-dual d = 6 string. A collection of N parallel fivebranes contains 12N(N–1) self-dual strings which become tensionless as the fivebranes approach one another.

Additional quotes by Andrew Strominger
Low-energy effective field theories arising from Calabi-Yau string compactifications are generically inconsistent or ill-defined at the classical level because of conifold singularities in the moduli space. It is shown, given a plausible assumption on the degenaracies of black hole states, that for type II theories this inconsistency can be cured by nonperturbative quantum effects: the singularities are resolved by the appearance of massless Ramond-Ramond black holes.
