Large N limit of non-commutative gauge theories
Using the correspondence between gauge theories and string theory in curved backgrounds, we investigate aspects of the large-N limit of non-commutative gauge theories by considering gravity solutionsExpand

Spinning strings in AdS(5) x S**5: New integrable system relations
A general class of rotating closed string solutions in AdS5 × S 5 is shown to be described by a Neumann-Rosochatius one-dimensional integrable system. The latter represents an oscillator on a sphereExpand

Spinning strings in AdS5 x S5 and integrable systems
We show that solitonic solutions of the classical string action on the AdS5 × S 5 background that carry charges (spins) of the Cartan subalgebra of the global symmetry group can be classified inExpand

Automorphic properties of low energy string amplitudes in various dimensions
This paper explores the moduli-dependent coefficients of higher derivative interactions that appear in the low-energy expansion of the four-supergraviton amplitude of maximally supersymmetric stringExpand

Low energy expansion of the four-particle genus-one amplitude in type II superstring theory
A diagrammatic expansion of coefficients in the low-momentum expansion of the genus-one four-particle amplitude in type II superstring theory is developed. This is applied to determine coefficientsExpand

Spinning strings in AdS5 × S5 and integrable systems
We show that solitonic solutions of the classical string action on the AdS5 × S5 background that carry charges (spins) of the Cartan subalgebra of the global symmetry group can be classified in termsExpand

Eisenstein series for higher-rank groups and string theory amplitudes
Scattering amplitudes of superstring theory are strongly constrained by the requirement that they be invariant under dualities generated by discrete subgroups, E_n(Z), of simply-laced Lie groups inExpand

String theory dualities and supergravity divergences
We demonstrate how duality invariance of the low energy expansion of the four-supergraviton amplitude in type II string theory determines the precise coefficients of multiloop logarithmic ultravioletExpand

Bagger-Lambert Theory for General Lie Algebras
We construct the totally antisymmetric structure constants f^{ABCD} of a 3-algebra with a Lorentzian bi-invariant metric starting from an arbitrary semi-simple Lie algebra. The structure constantsExpand
