Torons and D-brane bound states
We interpret instantons on a torus with twisted boundary conditions, in terms of bound states of branes. The interplay between the SU( N) and U(1) parts of the U( N) theory of N 4-branes allows the construction of a variety of bound states. The SU( N) and U(1) parts can contribute fractional amounts...

Summary: | We interpret instantons on a torus with twisted boundary conditions, in terms of bound states of branes. The interplay between the
SU(
N) and
U(1) parts of the
U(
N) theory of
N 4-branes allows the construction of a variety of bound states. The
SU(
N) and
U(1) parts can contribute fractional amounts to the total instanton number which is integral. The geometry of non-self-intersecting 2-cycles in
T
4 sheds some light on a number of properties of these solutions. |
