Abstract
A natural extension of the successful D3 - D 3-brane inflation model in string theory is one with two D3 - D 3-brane pairs, giving rise to a novel feature in string-theory. When the first pair annihilates, D1-strings and F1-strings are produced. Following the non-commutative geometric properties in string theory, it is shown by Myers that the presence of the D3-charge field strength of the remaining D3 - D 3-brane pair leads to the formation of dielectric 3-branes -- neutral, finite-size bound states of 3-branes with D1-strings. They behave as matter with little or no pressure. Spanning a wide range of masses, they seed primordial black holes in the early universe.
