The complex world of superstrings: On semichiral sigma models
Malin Göteman
Non-linear sigma models with extended supersymmetry have constrained target space geometries, and can serve as effective tools for investigating and constructing new geometries. An…

N=(4,4) supersymmetry and T-duality
Malin Goteman
A sigma model with four-dimensional target space parametrized by chiral and twisted chiral N=(2,2) superfields can be extended to N=(4,4) supersymmetry off-shell, but this is not t…
