TITLE:
Building Branes Out of Matrices
ABSTRACT:
We examine the set of objects which can be built in type IIA string theory by
matrix methods using an infinite number of D0-branes. In addition to
stacks of ordinary Dp-branes and branes in background fields, we find
exotic states which cannot be constructed by other means. These states
exhibit strongly noncommutative geometry, (e.g., partial derivatives on them
do not commute) and some are conjectured to have Z_N--valued
charges similar to those of the type I D-instanton. Real-valued charges are
forbidden by Dirac quantization, leading to a nontrivial relationship
between noncommutative topological invariants.
