Abstract
If one folds in two parts a strip of paper several times on itself (all folds being parallel) one obtains after unfolding a sequence of “valley” and “ridge” folds. If one codes these folds over a two-letter alphabet, one obtains a paperfolding word associated to the sequence of folding instructions. A paperfolding sequence is an infinite paperfolding word.
This paper is devoted to the effective construction of 2-uniform tag systems which generate every paperfolding sequences associated to ultimately periodic sequences of (un)folding instructions.
