Stable laws for heavy-tailed observables on polynomially mixing billiards
Matthew Nicol, Manpreet Singh, Andrew Torok
We investigate the competition between two distinct mechanisms generating stable laws in deterministic dynamical systems: slow mixing of the system and heavy-tailed observables. Fo…

Birkhoff sum convergence of Fréchet observables to stable laws for Gibbs-Markov systems and applications
An Chen, Matthew Nicol, Andrew Török
We use a Poisson point process approach to prove distributional convergence to a stable law for non square-integrable observables , mostly of the form $ϕ(x) = d(x,x_…
