%0 Journal Article %T D-instantons probing D3-branes and the AdS/CFT correspondence %A E. T. Akhmedov %J Physics %D 1998 %I arXiv %R 10.1103/PhysRevD.59.101901 %X D-instantons are considered as a probe of coinciding $N$ 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. %U http://arxiv.org/abs/hep-th/9812038v3
