Loop space blow-up and scale calculus
Urs Frauenfelder, Joa Weber
In this note we show that the Barutello-Ortega-Verzini regularization map is scale smooth.

Hilbert manifold structures on path spaces
Urs Frauenfelder, Joa Weber
In Floer theory one has to deal with two-level manifolds like for instance the space of loops and the space of loops. Gradient flow lines in Floer theory are th…

Floerfolds and Floer functions
Urs Frauenfelder, Joa Weber
In this article we introduce the notion of Floer function which has the property that the Hessian is a Fredholm operator of index zero in a scale of Hilbert spaces. Since the Hessi…

On the spectral flow theorem of Robbin-Salamon for finite intervals
Urs Frauenfelder, Joa Weber
In this article we consider operators of the form where lies in an interval and is continuous. Without boundary conditions these op…
