... alteration to the right side of (6) would be a change of c λ  to d λ  . One of the main aims of this paper is to deduce the form of Ω e l from that of Ω m u , which is given in the next equation. Ω e l T = ... determinants. In §2 the expansions of J ρ as determinants in e λ and m λ functions are given. The basic symmetry between these expansions is exhibited in §3, in...

Since E = ∅, we may allow in the definition of L(H), and in the minima in the following part of this proof, only subgraphs H with E(H) = ∅, and can conclude as follows: 1 L(H) = min H≤H |V ... ame-theoretic setting in Section 4. The definitions and proofing ideas in this section generalize the introduction of paintability of graphs in [Scha2] and the purely combina...

While an integrated system for processing and parsing speech may use both acoustic and syntactic information to find repairs, and thus may have access to some of this ... method for pars- ing speech that contains speech repairs. This system achieves high accuracy in both parsing and detecting reparanda in text, by making use of transformations that c...
