We include in F-theory, through open Type I F-theory branes (F-branes), string theories with N = 1 supersymmetry, both Type I and heterotic. Type I branes are distinguished from Type II by worldvolume parity projection. The same open Type I branes describe both open Type I superstrings and closed heterotic upon different sectionings from F-branes to worldsheets, while closed Type I superstrings arise from closed Type I branes. (Type II superstrings come from closed Type II branes, as described…

Double field theory of type II strings
We use double field theory to give a unified description of the low energy limits of type IIA and type IIB superstrings. The Ramond-Ramond potentials fit into spinor representations of the duality
Unification of type-II strings and T duality.
TLDR
A formulation that doubles the space-time coordinates in order to realize the T-duality group O(10,10) geometrically unifies the type-II theories in that each of them is obtained for a particular subspace of the doubled space.
Gauging unbroken symmetries in F-theory
F-theory attempts to include all U-dualities manifestly. Unlike its T-dual manifest partner, which is based on string current algebra, F-theory is based on higher dimensional brane current algebra.
Comments on T-Dualities of Ramond-Ramond Potentials
The type IIA/IIB effective actions compactified on T^d are known to be invariant under the T-duality group SO(d, d; Z) although the invariance of the R-R sector is not so direct to see. Inspired by a
Heterotic and type I string dynamics from eleven-dimensions
Abstract We propose that the ten-dimensional E 8 × E 8 heterotic string is related to an eleven-dimensional theory on the orbifold R 10 × S 1 / Z 2 in the same way that the Type IIA string in ten
Duality invariance: from M-theory to double field theory
We show how the duality invariant approach to M-theory formulated by Berman and Perry relates to the double field theory proposed by Hull and Zwiebach. In doing so we provide suggestions as to how
SO(d,d) Transformations of Ramond-Ramond Fields and Space-time Spinors
We explicitly construct the SO(d,d) transformations of Ramond-Ramond field strengths and potentials, along with those of the space-time supersymmetry parameters, the gravitinos and the dilatinos in
Ramond-Ramond gauge fields in superspace with manifest T-duality
A bstractA superspace with manifest T-duality including Ramond-Ramond gauge fields is presented. The superspace is defined by the double nondegenerate super-Poincaré algebras where Ramond-Ramond
Superspace with manifest T-duality from type II superstring
A bstractA superspace formulation of type II superstring background with manifest T-duality symmetry is presented. This manifestly T-dual formulation is constructed in a space spanned by two sets of
