Reducible Holonomy in Closed Torsion Geometries
Leander Stecker
The purpose of this note is to show that a connection with closed skewsymmetric torsion and reducible holonomy admits a locally defined Riemannian submersion together with a projec…

Canonical Submersions in Nearly Kähler Geometry
Leander Stecker
We explore submersions introduced by reducible holonomy representations of connections with parallel skew torsion. A submersion theorem extending previous, less general, results is…

The heterotic G system with reducible characteristic holonomy
Mateo Galdeano, Leander Stecker
We construct solutions to the heterotic G system on almost contact metric manifolds with reduced characteristic holonomy. We focus on --Sasaki manifolds and $(α,δ…
