The notion of parallel reduction is extracted from the simple proof of the Church-Rosser theorem by Tait and Martin-L f. Intuitively, this means to reduce a number of redexes (existing in a -term) simultaneously. Thus in the case of -reduction the effect of a parallel reduction is same as that of a "complete development" which is ...
WebDec 12, 2012 · Theorem \(\lambda\) is consistent, in the sense that not every equation is a theorem. To prove the theorem, it is sufficient to produce one underivable equation. We have already worked through an example: we used the Church-Rosser theorem to show that the equation \(\bK = \mathbf{I}\) is not a theorem of \(\lambda\). Of course, there’s ...
