Double complex cocycles for D-branes
نویسنده
چکیده
The cocycle approach to topological charge algebras is generalized to the case of D-branes. The D-brane has two associated cocycles, with an anomalous term of the Noether charge algebra deriving from each. The resulting topological charge algebras are extensions of the standard, background superalgebra by two disjoint, commuting ideals. The formalism is applied to (p, q)-strings and the D-membrane. The spectrum of topological charge algebras contains known algebras which allow the construction of extended superspace actions.

Double complex cocycles for p-branes
A double complex consisting of superspace forms under the action of the de Rham differential and a ghost field differential is introduced. A naturally associated single complex with a total differential D is defined. The Wess-Zumino term becomes a potential for a D cocycle associated with the p-brane. The algebras of generators of the left and right group actions are modified in the presence of...
متن کاملExtending lazy 2-cocycles on Hopf algebras and lifting projective representations afforded by them
We study some problems related to lazy 2-cocycles, such as: extension of (lazy) 2-cocycles to a Drinfeld double and to a Radford biproduct, Yetter-Drinfeld data obtained from lazy 2-cocycles, lifting of projective representations afforded by lazy 2-cocycles.
متن کاملSuperalgebras from p-brane actions
Two superalgebras associated with p-branes are the constraint algebra and the Noether charge algebra. Both contain anomalous terms which modify the standard supertranslation algebra. These anomalous terms have a natural description in terms of double complex cohomology of generalized forms. By retaining fermionic charges and allowing for gauge freedom in the double complex, it is shown that the...
متن کاملSupersymmetric D-branes on flux backgrounds
Several aspects concerning the physics of D-branes in Type II flux compactifications preserving minimal N = 1 supersymmetry in four dimensions are considered. It is shown how these vacua are completely characterized in terms of properly defined generalized calibrations for D-branes and the relation with Generalized Complex Geometry is discussed. General expressions for superpotentials and D-ter...
متن کاملCocycles, Compatibility, and Poisson Brackets for Complex Fluids
Motivated by Poisson structures for complex fluids containing cocycles, such as the Poisson structure for spin glasses given by Holm and Kupershmidt in 1988, we investigate a general construction of Poisson brackets with cocycles. Connections with the construction of compatible brackets found in the theory of integrable systems are also briefly discussed.
