TL;DR
This paper develops a T-duality invariant formulation of the massless sector of 3D Type II superstring theory in off-shell superspace, connecting it to higher-dimensional supergravity frameworks.
Contribution
It introduces a manifestly T-dual off-shell superspace formulation for 3D Type II superstrings, linking it to 4D supergravity and F-theory.
Findings
Provides a T-dual superspace action for 3D Type II superstrings.
Establishes a relation to 4D N=1 supergravity via 5D F-theory.
Identifies the pre potential as part of the vielbein without derivatives.
Abstract
We give the manifestly T-dual formulation of the massless sector of the classical 3D Type II superstring in off-shell 3D N=2 superspace, including the action. It has a simple relation to the known superspace of 4D N=1 supergravity in 4D M-theory via 5D F-theory. The pre potential appears as part of the vielbein, without derivatives.
