Gauss Paragraphs of Classical Links and a Characterization of Virtual Link Groups
A classical link in 3-space can be represented by a Gauss paragraph encoding a link diagram in a combinatorial way. A Gauss paragraph may code not a classical link diagram, but a diagram with virtual crossings. We present a criterion and a linear algorithm detecting whether a Gauss paragraph encodes a classical link. We describe Wirtinger presentations realizable by virtual link groups.
متن کاملSemantics of Paragraphs
We present a computational theory of the paragraph. Within it we formally define coherence, give semantics to the adversative conjunction "but" and to the Gricean maxim of quantity, and present some new methods for anaphora resolution. The theory precisely characterizes the relationship between the content of the paragraph and background knowledge needed for its understanding. This is achieved ...

متن کاملGenerating Coherent Paragraphs
Recent years have seen something of a divorce between models of computer-aided instruction and theories of second language learning. For example, it has come to be recognized that a satisfactory model of language teaching must incorporate the notion of 'communicative compe-tence', that is, not only the production of grammatically correct utterances, but also the appropriate use of utterances ac...
متن کاملA New Characterization of Plane Continuous Curves
A number of authorsf have given necessary and sufficient conditions that a bounded continuum be a continuous curve. However new conditions are always of interest as no one characterization applies without difficulty to all problems. It is the purpose of this paper to give a new necessary and sufficient condition that a bounded plane continuum be a continuous curve. Also this gives a condition u...
