BPS states on non-commutative tori and duality
Abstract
We study gauge theories on non-commutative tori. It has been proved that Morita equivalence of non-commutative tori leads to a physical equivalence ( SO(d, d/ Z)- duality) of the corresponding gauge theories [Nucl. Phys. B 534 (1998) 720]. We calculate the energy spectrum of maximally supersymmetric BPS states in these theories and show that this spectrum agrees with the SO(d, d/ Z)- duality. The relation of our results with those of recent calculations is discussed.
