Abstract

We define infinitary combinatory reduction systems (iCRSs). This provides the first extension of infinitary rewriting to higher-order rewriting. We lift two well-known results from infinitary term rewriting systems and infinitary λ-calculus to iCRSs: every reduction sequence in a fully-extended left-linear iCRS is compressible to a reduction sequence of length at most ω, and every complete development of the same set of redexes in an orthogonal iCRS ends in the same term.
