As top-down tree transducers generalize generalized sequential machines, shape preserving top-down tree transducers naturally generalize length preserving generalized sequential machines. For instance, top-down relabeling tree transducers are shape preserving top-down tree transducers. We show that
We introduce the bottom-up tree-to-graph transducer, which is very similar to the usual (total deterministic) bottom-up tree transducer except that it translates trees into hypergraphs rather than trees, using hypergraph substitution instead of tree substitution. If every output hypergraph of the tr
