Duality of type-II 7-branes and 8-branes
We present a version of ten-dimensional IIA supergravity containing a 9-form potential for which the field equations are equivalent to those of the standard, massless, IIA theory for vanishingExpand

Extended conformal supergravity
Abstract We present the complete structure of extended conformal supergravity for N ⩽4. The relation with the graded algebra SU(2, 2| N ) and with the multiplet of currents is discussed. The N = 4Expand

The quartic effective action of the heterotic string
We present the supersymmetric quartic effective action for the heterotic string which follows from the supersymmetrization of the Yang-Mills and Lorentz Chern-Simons forms. This includes all bosonicExpand

'Stringy' Newton-Cartan gravity
We construct a ‘stringy’ version of Newton–Cartan gravity in which the concept of a Galilean observer plays a central role. We present both the geodesic equations of motion for a fundamental stringExpand

Potential and mass-matrix in gauged N = 4 supergravity
We discuss the potential and mass-matrix of gauged N = 4 matter coupled supergravity for the case of six matter multiplets, extending previous work by considering the dependence on all scalars. WeExpand

Newtonian gravity and the Bargmann algebra
We show how the Newton-Cartan formulation of Newtonian gravity can be obtained from gauging the Bargmann algebra, i.e., the centrally extended Galilean algebra. In this gauging procedure severalExpand

Supersymmetric Chern-Simons terms in ten dimensions
Abstract We construct a supersymmetric extension of the Lorentz and Yang-Mills Chern-Simons terms in ten dimensions. In terms of dimensionful parameters α(Lorentz) and β (Yang-Mills), we obtain theExpand

Massive 3D supergravity
We construct the three-dimensional supergravity theory with cosmological, Einstein–Hilbert, Lorentz Chern–Simons, and general curvature squared terms. We determine the general supersymmetricExpand

Ten-dimensional Maxwell-Einstein supergravity, its currents, and the issue of its auxiliary fields
The d = 10, N = 1 Yang-Mills system is coupled to d = 10, N = 1 supergravity in a locally scale-invariant way. An analysis of the currents agrees with the Noether coupling results and reveals theExpand

D-branes and T duality
Abstract We show how the T-duality between D-branes is realized (i) on p-brane solutions (p = 0,…,9) of IIA IIB supergravity and (ii) on the D-brane actions (p = 0,…, 3) that act as source terms forExpand
