Multicore Noncommutative Bions
  The noncommutative bion core of Constable, Myers and Tafjord (hep-th/9911136) describes the BPS D1-D3 brane intersection (where a single bundle of D1-branes is attached to the D3 brane) in the nonabelian Born-Infeld theory of D1-branes. The possibility of extending this construction to BPS configurations with multiple separated parallel bundles of D1-branes attached to a single D3-brane is discussed. The problem is reduced to solving the Nahm equation with novel boundary conditions. A concrete, non-trivial solution is presented.
