Twisted Higgs bundles and coendoscopy

Michael Groechenig, Xuanyou Li, Dimitri Wyss +1

This short note is devoted to the study of $G$ -Higgs bundles twisted by a central gerbe. These objects arise naturally in the decomposition of the inertia stacks of $G$ -Higgs bundl…

Twisted points of quotient stacks, integration and BPS-invariants

Michael Groechenig, Dimitri Wyss, Paul Ziegler

We study $p$ -adic manifolds associated with twisted points of quotient stacks $X = [U / G]$ and their quotient spaces $I ¨ : X \to X$ . We prove several structural re…
