D-instantons probing D3-branes and the AdS/CFT correspondence

arXiv:hep-th/9812038 · doi:10.1103/PhysRevD.59.101901

Abstract

D-instantons are considered as a probe of coinciding D3-branes. They can feel an external metric via the commutator terms in their effective action. We show that when the D-instantons are separated from the D3-branes, the metric which is probed at the one loop level, {\it exactly} coincides with that of the BPS R-R 3-brane. Interesting connection of this result to the possible explanation of the AdS/CFT correspondence within IKKT M-atrix theory is discussed.
