Averages along cubes for not necessarily commuting measure preserving transformations

动力系统 2016-09-07 v1

摘要

We study the pointwise convergence of some weighted averages linked to averages along cubes. We show that if (X,B,μ,Ti)(X,\mathcal{B},\mu, T_i) are not necessarily commuting measure preserving systems on the same finite measure space and if fi,f_i, 1i61\leq i\leq 6 are bounded functions then the averages 1N3n,m,p=1Nf1(T1nx)f2(T2mx)f3(T3px)f4(T4n+mx)f5(T5n+px)f6(T6m+px)\frac{1}{N^3}\sum_{n, m, p=1}^N f_1(T_1^nx) f_2(T_2^mx) f_3(T_3^px) f_4(T_4^{n+m}x) f_5(T_5^{n+p}x) f_6(T_6^{m+p}x) converge almost everywhere.
