D-Instantons in the AdS/CFT Correspondence
Abstract:- A review of D-instantons in IIB superstring theory and their relation
to instantons in N=4 super-Yang-Mills via the AdS/CFT duality is given.
These methods are applied to conformal N=2 theories which can be realized
as orientifolds of IIB. Heterotic / type I' duality is used to calculate
D-instanton contributions exactly and relate them to Yang-Mills instanton
contributions, which can in principle be calculated by ADHM-calculus.
