DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OWNS/17/">Ra
 ndom matching for random interval maps</a>\nby Marta Maggioni (Leiden Univ
 ersity) as part of One World Numeration seminar\n\n\nAbstract\nIn this tal
 k we extend the notion of matching for deterministic transformations to ra
 ndom matching for random interval maps. For a large class of piecewise aff
 ine random systems of the interval\, we prove that this property of random
  matching implies that any invariant density of a stationary measure is pi
 ecewise constant. We provide examples of random matching for a variety of 
 families of random dynamical systems\, that includes generalised beta-tran
 sformations\, continued fraction maps and a family of random maps producin
 g signed binary expansions. We finally apply the property of random matchi
 ng and its consequences to this family to study minimal weight expansions.
  \nBased on a joint work with Karma Dajani and Charlene Kalle.\n
