Center node: "well definedness of streams by transformation and termination"
  Abstract: Streams are infinite sequences over a given data type. A stream specification#N#is a set of equations intended to define a stream. We propose a transformation#N#from such a stream specification to a term rewriting system (TRS) in such a way#N#that termination of the resulting TRS implies that the stream specification is#N#well-defined, that is, admits a unique solution. As a consequence, proving#N#well-definedness of several interesting stream specifications can be done fully#N#automatically using present powerful tools for proving TRS termination. In#N#order to increase the power of this approach, we investigate transformations#N#that preserve semantics and well-definedness. We give examples for which the#N#above mentioned technique applies for the ransformed specification while it#N#fails for the original one.
