DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BODS/22/">Re
 newal and ratio mixing properties of "nice" infinite ergodic transformatio
 ns</a>\nby Jon Aaronson (Tel Aviv University) as part of Bremen Online Dyn
 amics Seminar\n\n\nAbstract\nI'll discuss "ratio mixing"  properties\nof  
 transformations preserving infinite measures ( e.g. as in  Hopf's\n1936 bo
 ok) and also their "renewal properties"\n(occupation processes to sets of 
 finite measure). Examples of "nice"\ntransformations considered include ce
 rtain null-recurrent Markov\nchains\, - "intermittent" interval maps\, - i
 nner functions\, hyperbolic\ngeodesic flows on cyclic covers.\n\nIncludes 
 joint work with Hitoshi Nakada\, Dalia Terhesiu & Toru Sera.\n
