Torsion, as a function on the space of representations
Dan Burghelea, Stefan Haller
Riemannian Geometry, Topology and Dynamics permit to introduce partially defined holomorphic functions on the variety of representations of the fundamental group of a manifold. The…
The geometric complex of a Morse-Bott-Smale pair and an extension of a theorem by Bismut-Zhang
Dan Burghelea, Stefan Haller
We define the geometric complex associated to a Morse-Bott-Smale vector field, cf. [Austin-Braam, 1995], and its associated spectral sequence. We prove an extension of the Bismut-Z…
Laplace transform, dynamics and spectral geometry
Dan Burghelea, Stefan Haller
We consider vector fields on a closed manifold with rest points of Morse type. For such vector fields we define the property of exponential growth. A cohomology class $ξ\in…
Non-linear Grassmannians as coadjoint orbits
Stefan Haller, Cornelia Vizman
For a given manifold we consider the non-linear Grassmann manifold of -dimensional submanifolds in . A closed -form on gives rise to a closed 2-form…
A remark on the c--splitting conjecture
Stefan Haller
Let be a closed symplectic manifold and suppose is a Hamiltonian fibration. Lalonde and McDuff raised the question whether one always has $H^*(P;\mathbb Q)=H^*(M;…
Smooth perfectness through decomposition of diffeomorphisms into fiber preserving ones
Stefan Haller, Josef Teichmann
We show that on a closed smooth manifold equipped with fiber bundle structures whose vertical distributions span the tangent bundle, every smooth diffeomorphism of …
