In this paper we provide an automaton-based solution to the decision problem for a large set of monadic second-order theories of deterministic tree structures. We achieve it in two...
Many useful XML transformations can be formulated through deterministic top-down tree transducers. A canonical form for such transducers is presented which allows to decide equiva...
In this paper we generalize the contraction method, originally proposed by Elgot and Rabin and later extended by Carton and Thomas, from labeled linear orderings to colored determ...
The pebble tree automaton and the pebble tree transducer are enhanced by additionally allowing an unbounded number of `invisible' pebbles (as opposed to the usual `visible...
