Pointwise convergence of certain continuous-time double ergodic averages

Michael Christ, Polona Durcik, Vjekoslav Kovač +1

We prove a.e. convergence of continuous-time quadratic averages with respect to two commuting -actions, coming from a single jointly measurable measure-preserving $\mat…

Norm-variation of ergodic averages with respect to two commuting transformations

Polona Durcik, Vjekoslav Kovač, Kristina Ana Škreb +1

We study double ergodic averages with respect to two general commuting transformations and establish a sharp quantitative result on their convergence in the norm. We approach the p…

Quantitative norm convergence of double ergodic averages associated with two commuting group actions

Vjekoslav Kovač

We study double averages along orbits for measure preserving actions of , the direct sum of countably many copies of a finite abelian group . In this arti…
