%0 Journal Article %T Renormalization and conjugacy of piecewise linear Lorenz maps %A Hong-Fei Cui %A Yi-Ming Ding %J Mathematics %D 2009 %I arXiv %X For each piecewise linear Lorenz map that expand on average, we show that it admits a dichotomy: it is either periodic renormalizable or prime. As a result, such a map is conjugate to a $\beta$-transformation. %U http://arxiv.org/abs/0906.3131v3
