Lagrange multipliers and adiabatic limits I
Urs Frauenfelder, Joa Weber
Critical points of a function subject to a constraint can be either detected by restricting the function to the constraint or by looking for critical points of the Lagrange multipl…
The regularized free fall II -- Homology computation via heat flow
Urs Frauenfelder, Joa Weber
In [BOV20] Barutello, Ortega, and Verzini introduced a non-local functional which regularizes the free fall. This functional has a critical point at infinity and therefore does not…
Scale Calculus and M-Polyfolds -- An Introduction
Joa Weber
These are lecture notes on scale calculus and M-polyfolds written for a graduate course at UNICAMP March-June 2018 and an advanced mini-course given during the biannual meeting of…
The fine structure of Weber's hydrogen atom -- Bohr-Sommerfeld approach
Urs Frauenfelder, Joa Weber
In this paper we determine in second order in the fine structure constant the energy levels of Weber's Hamiltonian admitting a quantized torus. Our formula coincides with the formu…
The shift map on Floer trajectory spaces
Urs Frauenfelder, Joa Weber
In this article we give a uniform proof why the shift map on Floer homology trajectory spaces is scale smooth. This proof works for various Floer homologies, periodic, Lagrangian,…
Topological Methods in the Quest for Periodic Orbits
Joa Weber
These are lecture notes on Floer and Rabinowitz-Floer homology written for a graduate course at UNICAMP August-December 2016 and a mini-course held at IMPA in August 2017.
