Lagrangian singularities of invariant tori of hamiltonian systems with two degrees of freedom.
Lagrangian theory for presymplectic systems
Lagrangian tori in a sympletic vector space and global symplectomorphisms.
Languages of finite words occurring infinitely many times in an infinite word
We give necessary and sufficient conditions for a language to be the language of finite words that occur infinitely many times in an infinite word.

Large deviations asymptotics and the spectral theory of multiplicatively regular Markov processes.
Large deviations for generic stationary processes
Let (Ω,A,μ,T) be a measure preserving dynamical system. The speed of convergence in probability in the ergodic theorem for a generic function on Ω is arbitrarily slow.

Large sets of integers and hierarchy of mixing properties of measure preserving systems
We consider a hierarchy of notions of largeness for subsets of ℤ (such as thick sets, syndetic sets, IP-sets, etc., as well as some new classes) and study them in conjunction with recurrence in topological dynamics and ergodic theory. We use topological dynamics and topological algebra in βℤ to establish connections between various notions of largeness and apply those results to the study of the sets of times of “fat intersection”. Among other things we show that the sets allow one to distinguish...
