Non-relativistic superstrings: a new soluble sector of AdS5 × S5
We find a new sector of string theory in AdS5 × S5 describing non-relativistic superstrings in that geometry. The worldsheet theory of non-relativistic strings in AdS5 × S5 is derived and shown toExpand

Hamiltonian formalism for space-time noncommutative theories
Departament de F´isica Fonamental, Universitat de Barcelona, Diagonal 647, E-08028 Barcelona, SpainSpace-time non-commutative theories are non-local in time. We develop the Hamiltonian formal-ism forExpand

Gauge theory of two-dimensional gravity
Abstract The theory of gravity in two dimensions is discussed as a O(2,1) gauge theory. The pure gauge system gives a geometrical equation in which the riemannian curvature is a constant. We obtainExpand

Non-relativistic superbranes
Subtleties arising in the non-relativistic limit of relativistic branes are resolved, and a reparametrization-invariant and kappa-symmetric non-relativistic super p-brane action is obtained as aExpand

Generalized cosmological term from Maxwell symmetries
By gauging the Maxwell spacetime algebra the standard geometric framework of Einstein gravity with cosmological constant term is extended by adding six fourvector fields A_\mu^{ab}(x) associated withExpand

Type II chiral affine Lie algebras and string actions in doubled space
A bstractWe present affine Lie algebras generated by the supercovariant derivatives and the supersymmetry generators for the left and right moving modes in the doubled space. Chirality is manifest inExpand

Maxwell superalgebra and superparticles in constant gauge backgrounds.
We present the Maxwell superalgebra, an N=1, D=4 algebra with two Majorana supercharges, obtained as the minimal enlargement of a Poincaré superalgebra containing the Maxwell algebra as a subalgebra.Expand

Electric-magnetic duality invariant Lagrangians
Abstract We find general non-linear Lagrangians invariant under the electric-magnetic duality. They are characterized by an arbitrary function and are reduced to the Maxwell theory in weak fieldExpand

SL(5) duality from canonical M2-brane
A bstractWe show how the SL(5) duality in M-theory is explained from a canonical analysis of M2-brane mechanics. Diffeomorphism constraints for a M2-brane coupled to supergravity background in d = 4Expand

Super-pp-wave algebra from super-AdS×S algebras in eleven dimensions
Abstract Maximally supersymmetric spacetime algebras in eleven dimensions, which are the isometry superalgebras of Minkowski space, AdS7×S4, AdS4×S7 and pp-wave background, are related byExpand
