M-theory and Type IIB from a Duality Manifest Action
Chris D. A. Blair, Emanuel Malek, Jeong-Hyuck Park
We revisit the SL(5) U-duality manifest action constructed by Berman and Perry in an extended spacetime. Upon choosing a four-dimensional solution to the section condition constrai…
An O(D,D) Invariant Hamiltonian Action for the Superstring
Chris D. A. Blair, Emanuel Malek, Alasdair J. Routh
We construct O(D,D) invariant actions for the bosonic string and RNS superstring, using Hamiltonian methods and ideas from double field theory. In this framework the doubled coordi…
The O_{D,D} Geometry of String Theory
David S. Berman, Chris D. A. Blair, Emanuel Malek +1
We construct an action for double field theory using a metric connection that is compatible with both the generalised metric and the O_{D,D} structure. The connection is simultaneo…
Timelike U-dualities in Generalised Geometry
Emanuel Malek
We study timelike U-dualities acting in three and four directions of 11-dimensional supergravity, which form the groups and SL(5). Using generalised geometry, w…
