Abstract
We investigate non-extremal D-instantons in an asymptotically AdS5 × S5 background
and the role they play in the AdS5/CFT4 correspondence. We find that the
holographic dual operators of non-extremal D-instanton configurations do not correspond
to self-dual Yang-Mills instantons, and we compute explicitly the deviation
from self-duality.
Furthermore, a class of non-extremal D-instantons yield Euclidean axionic
