Ramond-ramond Fields, Fractional Branes and Orbifold Differential K-theory
We study D-branes and Ramond-Ramond fields on global orbifolds of Type II string theory with vanishing H-flux using methods of equivariant K-theory and K-homology. We illustrate how Bredon equivariant cohomology naturally realizes stringy orbifold cohomology. We emphasize its role as the correct cohomological tool which captures known features of the low-energy effective field theory, and which...
متن کاملSelf-Duality, Ramond-Ramond Fields, and K-Theory
Just as D-brane charge of Type IIA and Type IIB superstrings is classified, respectively, by K(X) and K(X), Ramond-Ramond fields in these theories are classified, respectively, by K(X) and K(X). By analyzing a recent proposal for how to interpret quantum self-duality of RR fields, we show that the Dirac quantization formula for the RR p-forms, when properly formulated, receives corrections that...
متن کاملK-theory and Ramond-Ramond charge
We discuss the relation between the Ramond-Ramond charges of D-branes and the topology of Chan-Paton vector bundles. We show that a topologically nontrivial normal bundle induces RR charge and that the result fits in perfectly with the proposal that D-brane charge is the topology of the Chan-Paton bundle, regarded as an element of K
متن کاملRamond-Ramond Couplings of Noncommutative D-branes
We propose the leading couplings, in an α expansion, of D-branes to Ramond-Ramond (RR) potentials in a constant NSNS B-field for an arbitrary choice of noncommutative parameter. The proposal is motivated by some string amplitude computations. The zero momentum couplings are topological in nature and include Elliott’s formula involving the noncommutative Chern character. The finite momentum coup...
متن کاملDirichlet Branes and Ramond-Ramond charges.
We show that D-branes, extended objects defined by mixed Dirichlet-Neumann boundary conditions, break half the supersymmetries of the type II superstring and carry a complete set of electric and magnetic Ramond-Ramond charges. The product of the electric and magnetic charges is a single Dirac unit, and the quantum of charge is that required by string duality. This is strong evidence that D-bran...
