In this paper, which is written at an elementary and pedagogical level, we discuss general aspects of (single) instantons in SU(N) Yang-Mills theory, and then specialize to the case of = 4 supersymmetry and the large-N limit. We show how to determine the measure of collective coordinates and compute instanton corrections to certain correlation functions. We then relate this to D-instantons in type IIB supergravity. By taking the D-instantons to live in an AdS5×S5 background, we perform explicit… 
Generalized instantons in N = 4 super Yang-Mills theory and spinorial geometry
Using spinorial geometry techniques, we classify the supersymmetric solutions of euclidean = 4 super Yang-Mills theory. These backgrounds represent generalizations of instantons with nontrivial
Classical gauge instantons from open strings
We study the D3/D(-1) brane system and show how to compute instanton corrections to correlation functions of gauge theories in four dimensions using open string techniques. In particular we show that
Instanton calculations for N = 1/2 super Yang-Mills theory
We study (anti-) instantons in super Yang-Mills theories defined on a non anticommutative superspace. The instanton solution that we consider is the same as in ordinary SU(2) N = 1 super Yang-Mills,
Eisenstein Series and Instantons in String Theory
In this thesis we review U-duality constraints on corrections to the type IIB supergravity effective action on torus compactifications. The U-duality invariant corrections are described by
D-instantons and multiparticle production in N=4 SYM
N=4 Super-symmetric Yang-Mills theory (N=4 SYM) in the strong coupling regime has been successfully applied (through the AdS/CFT correspondence) to the description of strongly coupled plasma which is
d-Brane Instantons in Type II Orientifolds
We review recent progress in determining the effects of d-brane instantons in supersymmetric compactifications of Type II string theory to four dimensions. We describe the abstract d-brane instanton
Supersymmetric D3-branes in five-form flux
We consider multiple euclidean D3-branes in a specific supergravity solution, which consists of a self-dual 5-form RR field in a flat background. We propose a deformation of = 4 SYM action describing
Non-perturbative effects in the BMN limit of Script N=4 supersymmetric Yang-Mills
One-instanton contributions to the correlation functions of two gauge-invariant single-trace operators in = 4 SU(N) Yang-Mills theory are studied in semi-classical approximation in the BMN limit. The
Non-extremal D-instantons and the AdS/CFT correspondence
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


Instantons in supersymmetric Yang-Mills and D instantons in IIB superstring theory
The one-instanton contributions to various correlation functions of superconformal currents in four-dimensional = 4 supersymmetric SU(2) Yang-Mills theory are evaluated to the lowest order in
Multi - instantons and Maldacena's conjecture
We examine certain n-point functions Gn in = 4 supersymmetric SU(N) gauge theory at the conformal point. In the large-N limit, we are able to sum all leading-order multi-instanton contributions
Non-perturbative Effects in AdS5 * S5 String Theory and d=4 SUSY Yang--Mills
We show that five-dimensional anti de-Sitter space remains a solution to low-energy type IIB supergravity when the leading higher-derivative corrections to the classical supergravity (which are
