We review different exact approaches to string theory. In the context of the Green–Schwarz
superstring, we discuss the action in curved backgrounds and its supercoset formulation …

We investigate the AdS 3/CFT 2 correspondence for theories with 16 supercharges using
the integrability approach. We construct Green-Schwarz actions for Type IIB strings on AdS …

In this review, a general procedure to represent the integral Bethe Ansatz equations in the
form of the Reimann–Hilbert problem is given. This allows us to study integrable spin chains …

We use integrability techniques to compute structure constants in\(\mathcal {N}= 4\) SYM to
leading order at weak coupling and to leading order in the planar expansion. Three closed …

We investigate the integrable structure of spin chain models with centrally extended and
symmetry. These chains have their origin in the planar anti-de Sitter/conformal field theory …

We propose a set of Bethe equations yielding the full asymptotic spectrum of the AdS 4/CFT
3 duality proposed in arxiv: 0806.1218 to all orders in the t'Hooft coupling. These equations …

We calculate the holographic three-point functions in\(\mathcal {N}= 4\) super-Yang-Mills
theory in the case when two of the operators are semiclassical and one is dual to a …

We study the classical spectrum of string theory on AdS 5× S 5 in the Hofman-Maldacena
limit. We find a family of classical solutions corresponding to Giant Magnons with two …

Motivated by a desire to find a useful 2d Lorentz-invariant reformulation of the AdS5× S5
superstring world-sheet theory in terms of physical degrees of freedom we construct the …

We compute form factors in planar\(\mathcal {N}= 4\) Super Yang-Mills at strong coupling.
Namely we consider the overlap between an operator insertion and 2n gluons. Through the …
