DESCRIPTION:Speaker: Runlian Xia (University of Glasgow)\n\nTitle: Ergodi
 c theorems for unimodular amenable groups via random walk approach\n\nAb
 stract: The pointwise ergodic theorem for amenable groups was first prov
 ed by Lindenstrauss in 2001. Very recently\, this result was extended to
  the noncommutative setting - where the measure space is replaced by a v
 on Neumann algebra equipped with a semifinite normal faithful trace - by
  Caldihac and Wang. In this talk\, we show that the ergodic averages of 
 the action of any unimodular amenable group along certain Følner sequenc
 es can be dominated by the Cesàro means of a suitably constructed Markov
  operator\; that is\, by the ergodic averages of an integer action. As a
  consequence\, we provide a unified and simpler proof of the two results
  in the commutative and noncommutative setting for unimodular amenable g
 roups.\n\nJoint work with Ujan Chakraborty and Joachim Zacharias. \n   \
