# Spectral analysis workshop in Banff

The workshop Spectral Analysis, Stability and Bifurcation in Modern Nonlinear Physical Systems took place at the Banff International Research Station between 4 and 9 November 2012. In the workshop I gave an invited talk on the recent work about using covering maps to prove fractional monodromy in 2-DOF integrable Hamiltonian systems in $$n_1{:}-n_2$$ resonance. The video of the presentation is available from the BIRS website.
