The Equivalence Problem for Deterministic MSO Tree Transducers Is Decidable
It is decidable for deterministic MSO definable graph-to-string or graphto-tree transducers whether they are equivalent on a context-free set of graphs. It is well known that the equivalence problem for nondeterministic (one-way) finite state transducers is undecidable, even when they cannot read or write the empty string [Gri68]. In contrast, equivalence is decidable for deterministic finite s...
متن کاملNode Query Preservation for Deterministic Linear Top-Down Tree Transducers
This paper discusses the decidability of node query preservation problems for XML document transformations. We assume a transformation given by a deterministic linear top-down data tree transducer (abbreviated as DLTV ) and an n-ary query based on runs of a tree automaton. We say that a DLTV Tr strongly preserves a query Q if there is a query Q′ such that for every document t, the answer set of...
متن کاملDeterministic Top-Down Tree Transducers with Iterated Lookahead
It is known that by iterating the look-ahead tree languages for deterministic topdown tree automata, more and more powerful recognizing devices are obtained. Let DR0 = DR, where DR is the class of all tree languages recognizable by deterministic top-down tree automata, and let, for n 1, DRn be the class of all tree languages recognizable by deterministic top-down tree automata with DRn 1 lookah...
متن کاملTop-Down Tree-To-Graph Transducers
We introduce a new syntax-directed translation device called top-down treeto-graph transducer. Such transducers are very similar to the usual top-down tree trans ducers except that the right-hand sides of their rules are hypergraphs rather than trees. Since we are aiming at a device which also allows to translate trees into objects ditTerent from graphs, we focus our attention on so-called tree...
متن کاملCompositions of Extended Top-down Tree Transducers
Unfortunately, the class of transformations computed by linear extended top-down tree transducers with regular look-ahead is not closed under composition. It is shown that the class of transformations computed by certain linear bimorphisms coincides with the previously mentioned class. Moreover, it is demonstrated that every linear epsilon-free extended top-down tree transducer with regular loo...
