Extended Riemannian Geometry I: Local Double Field Theory
Andreas Deser, Christian Saemann
We present an extended version of Riemannian geometry suitable for the description of current formulations of double field theory (DFT). This framework is based on graded manifolds…
The 2-Hilbert Space of a Prequantum Bundle Gerbe
Severin Bunk, Christian Saemann, Richard J. Szabo
We construct a prequantum 2-Hilbert space for any line bundle gerbe whose Dixmier-Douady class is torsion. Analogously to usual prequantisation, this 2-Hilbert space has the catego…
Higher Groupoid Bundles, Higher Spaces, and Self-Dual Tensor Field Equations
Branislav Jurco, Christian Saemann, Martin Wolf
We develop a description of higher gauge theory with higher groupoids as gauge structure from first principles. This approach captures ordinary gauge theories and gauged sigma mode…
