Connections on central extensions, lifting gerbes, and finite-dimensional obstruction vanishing
Indranil Biswas, Markus Upmeier
Given a central extension of Lie groups, we study the classification problem of lifting the structure group together with a given connection. For reductive structure groups we intr…

Extremal K-contact metrics
Mehdi Lejmi, Markus Upmeier
Extending a result of He to the non-integrable case of K-contact manifolds, it is shown that transverse Hermitian scalar curvature may be interpreted as a moment map for the strict…

Refinements of the Chern-Dold Character: Cocycle Additions in Differential Cohomology
Markus Upmeier
The Chern-Dold character of a cohomology theory E is a canonical transformation to ordinary cohomology. A spectrum representing E gives homotopy theoretic cocycle…
