From the point of view of the D1-brane the configuration is described by the D1-brane opening up into a D3-brane where the extra three dimensions form a fuzzy two-sphere whose radius diverges at the origin of the D3-brane.
It was showed in [10] that the BI action, when taken as the fundamental action, can be used to build a configuration with a semi-infinite fundamental string ending on a D3-brane [11].
i], i = 1, 2, 3 represent the D-string expanding into a D3-brane analogous to the bion solution of the D3-brane theory [2, 3].
