Abstract
We propose a way to identify the gauge invariant operator in noncommutative gauge theory on a D-brane with nonzero B field which couples to a specific supergravity mode in the bulk. This uses the description of noncommutative gauge theories in terms of ordinary gauge theories in lower dimensions. The proposal is verified in the DBI approximation. Other authors have shown that the proposal is also consistent with explicit string worldsheet calculations. We comment on implications to holography.
