The fundamental string can begin and end either at the same or different D-branes. Since the string is oriented, there are four massless vector states when the branes are practically on the top of each other. They form a representation of U(2). - "Three …

Webmodel of this kind was the so-called NBI matrix model of IIB superstrings with the potential XΛ + X−1 + (2η + 1)logX appeared [11, 12] in the context of the (M)atrix string theory. This model includes the BG model as a particular case (η = 0) [13] and away of this point, it can be reduced [14], after the time changing, to the Kontsevich model.
