Deformations of quasi-Hamiltonian spaces
Jean-Philippe Burelle, Mohamed Moussadek Maiza, Maxence Mayrand
We introduce a notion of deformations of quasi-Hamiltonian -spaces to Hamiltonian -spaces and provide several examples. In particular, we show that the double of…

Products of exact dynamical systems and Lorentzian continued fractions
Brandon G. Barreto-Rosa, Jean-Philippe Burelle, Anton Lukyanenko +1
We describe a new continued fraction system in Minkowski space , proving convergence, ergodicity with respect to an explicit invariant measure, and Lagrange's theo…

Proper affine deformations of positive representations
Jean-Philippe Burelle, Neža Žager Korenjak
We define for every positive Anosov representation of a nonabelian free group into a family of -valued cocycles which induce proper affine…
