The Ergodic Decomposition of Infinite Pickrell Measures III. The infinite Bessel process as the limit of radial parts of finite-dimensional projections of infinite Pickrell measures
Alexander I. Bufetov
The third part of the paper concludes the proof of the main result --- the description of the ergodic decomposition of infinite Pickrell measures. First it is shown that the scalin…
Infinite Determinantal Measures and The Ergodic Decomposition of Infinite Pickrell Measures II. Convergence of determinantal measures
Alexander I. Bufetov
The second part of the paper mainly deals with convergence of infinite determinantal measures, understood as the convergence of the approximating finite determinantal measures. In…
Topological dynamics of piecewise λ-affine maps
Arnaldo Nogueira, Benito Pires, Rafael A. Rosales
Let and be a piecewise -affine map, that is, there exist points and real numbers such that $f(…
Weak-mixing polygonal billiards
Alba Málaga Sabogal, Serge Troubetzkoy
We consider the set of polygons all of whose sides are vertical or horizontal with fixed combinatorics (for example all the figure "L"s). We show that there is a dense G subset…
Counting problem on wind-tree models
Angel Pardo
We study periodic wind-tree models, billiards in the plane endowed with -periodically located identical connected symmetric right-angled obstacles. We show asymptotic…
Topological substitutions and Rauzy fractals
Nicolas Bédaride, Arnaud Hilion, Timo Jolivet
We consider two families of planar self-similar tilings of different nature: the tilings consisting of translated copies of the fractal sets defined by an iterated function system,…
