... not contain a string zpa together with zpb (where a ~ b) or together with zpf. It is clear that the property of a reg- ular language L of being dash-free with respect to L and A can be read ... may ap- pear only as terminal nodes. The edges are la- beled with features and for every node no two outgoing edges may be labeled with the same feature. We formalize feature graphs a...

... every frontier node is labeled with a terminal (thus no nodes are marked for substitution.) We refer to the set of all trees, both initial and auxiliary, with or without nodes marked for substitution, ... of Q) with finite domain, the transi- tion function. The transition function M associates sets of states with alphabet symbols. It induces a function that as- sociates sets of s...
