%0 Journal Article %T Weak Closure Theorem for Double Staircase Actions %A V. V. Ryzhikov %J Mathematics %D 2011 %I arXiv %X We introduce a double staircase construction $T$ and show that the weak closure of $\{T^n\}$ is $\{\int, 2^{-m}T^n+(1-2^{-m})\int \ : m\in\N,\ n\in \Z\}.$ %U http://arxiv.org/abs/1108.0568v1
