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…

Smooth perfectness for the group of diffeomorphisms
Stefan Haller, Tomasz Rybicki, Josef Teichmann
Given a result of Herman, we provide a new elementary proof of the fact that the connected component of the group of compactly supported diffeomorphisms is perfect and hence simple…

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…
