DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OWNS/90/">Ra
 ndom Lüroth expansions</a>\nby Charlene Kalle (Universiteit Leiden) as pa
 rt of One World Numeration seminar\n\n\nAbstract\nSince the introduction o
 f Lüroth expansions by Lüroth in his paper from 1883 many results have a
 ppeared on their approximation properties. In 1990 Kalpazidou\, Knopfmache
 r and Knopfmacher introduced alternating Lüroth expansions and studied th
 eir properties. A comparison between the two and other comparable number s
 ystems was then given by Barrionuevo\, Burton\, Dajani and Kraaikamp in 19
 96. In this talk we introduce a family of random dynamical systems that pr
 oduce many Lüroth type expansions at once. Topics that we consider are pe
 riodic expansions\, universal expansions\, speed of convergence and approx
 imation coefficients. This talk is based on joint work with Marta Maggioni
