Homogeneous spinor flow
Marco Freibert, Lothar Schiemanowski, Hartmut Weiss
We study the spinor flow on homogeneous spin manifolds. After providing the general setup we discuss the homogeneous spinor flow in dimension 3 and on almost abelian Lie groups in…
Limiting configurations for solutions of Hitchin's equation
Rafe Mazzeo, Jan Swoboda, Hartmut Weiss +1
We review recent work on the compactification of the moduli space of Hitchin's self-duality equation. We study the degeneration behavior near the ends of this moduli space in a set…
The variation formulas for the equivariant Ray-Singer metric
Hartmut Weiss
We give a new and detailed proof of the variation formulas for the equivariant Ray-Singer metric, which are originally due to J.M. Bismut and W. Zhang.
The Laplacian on hyperbolic 3-manifolds with Dehn surgery type singularities
Frank Pfaeffle, Hartmut Weiss
We study the spectrum of the Laplacian on hyperbolic 3-manifolds with Dehn surgery type singularities and its dependence on the generalized Dehn surgery coefficients.
