%0 Journal Article %T A new multidimensional slow continued fraction algorithm and stepped surface %A Maki Furukado %A Shunji Ito %A Asaki Saito %A Jun-ichi Tamura %A Shin-ichi Yasutomi %J Mathematics %D 2013 %I arXiv %X We give a new algorithm of slow continued fraction expansion related to any real cubic number field as a 2-dimensional version of the Farey map. Using our algorithm, we can find the generators of dual substitutions (so-called tiling substitutions) for any stepped surface for any cubic direction. %U http://arxiv.org/abs/1310.7781v1
