Abstract The fields of the conjectured “heterotic” super-fivebrane sigma model in ten dimensions are made out of a well-known gravitational sector, the X and the ϑ, and of a still unknown heterotic sector which should be coupled to the Yang-Mills fields. We compute the one-loop d = 6 world-volume and D = 10 target-space Lorentz anomalies which arise from the gravitational sector of the heterotic super-fivebrane sigma model, using a method which we developed previously for the Green-Schwarz… Expand
Fivebrane Structures
We study the cohomological physics of fivebranes in type II and heterotic string theory. We give an interpretation of the one-loop term in type IIA, which involves the first and second PontrjaginExpand
Quantum properties of the heterotic five-brane
Abstract We find that the conjectured heterotic SO ( 32 ) five-brane sigma model develops necessarily k-anomalies, and we investigate their form. We show that these anomalies can be absorbed byExpand
Gauge Enhancement of Super M-Branes Via Parametrized Stable Homotopy Theory
AbstractA key open problem in M-theory is to explain the mechanism of “gauge enhancement” through which M-branes exhibit the nonabelian gauge degrees of freedom seen perturbatively in the limit ofExpand
Twisted Differential String and Fivebrane Structures
In the background effective field theory of heterotic string theory, the Green-Schwarz anomaly cancellation mechanism plays a key role. Here we reinterpret it and its magnetic dual version in termsExpand
D-branes in non-tachyonic 0B orientifolds
Abstract We determine all D-branes in the non-tachyonic 0'B orientifold, examine their worldvolume anomalies and study orbifold compactifications. We find that the spectrum of the D-branes containsExpand
Abstract The anomaly due to the chiral fermions on the world-volume of the SO (32) five-brane is calculated. It is shown that this contribution has the correct structure for it to be cancelled by theExpand
The non-perturbative SO(32) heterotic string
Abstract The SO (32) heterotic string can be obtained from the type IIB string by gauging a discrete symmetry that acts as (−1) F L on the perturbative string states and reverses the parity of theExpand
The cancellation of world-sheet anomalies in the D = 10 Green-Schwarz heterotic string sigma model☆
We determine the two-dimensional Weyl, Lorentz and κ-anomalies in the D = 10 Green-Schwarz heterotic string sigma model, in an SO(1, 9) Lorentz-covariant background gauge, and prove theirExpand
Real ADE-Equivariant (co)Homotopy and Super M-Branes
A key open problem in M-theory is the identification of the degrees of freedom that are expected to be hidden at ADE-singularities in spacetime. Comparison with the classification of D-branes byExpand
Higher T-duality of super M-branes
We establish a higher generalization of super L-infinity-algebraic T-duality of super WZW-terms for super p-branes. In particular, we demonstrate spherical T-duality of super M5-branes propagating onExpand
