Special Lagrangian submanifolds and circle collapse on K3
Sébastien Picard, Federico Trinca
We consider surfaces collapsing to a three-dimensional affine base. We show that certain affine lines on the base lift to degenerating sequences of special Lagrangian two-sphe…

Stringy Corrections to Heterotic SU(3)-Geometry
Jock McOrist, Sebastien Picard
We analyse the corrections to the supersymmetry transformations constructed by Bergshoeff--de Roo for heterotic compactifications on SU(3) manifolds. The internal geometry r…

Balanced and Aeppli Parameters for the Heterotic Moduli
Sébastien Picard, Pei-Lin Wu
In this paper, we fix the complex structure and explore the moduli space of the heterotic system by considering two different yet "dual" deformation paths starting from a Kähler s…
