Higher-Order Rewrite Systems and Their Confluence


We introduce Higher-Order Rewrite Systems (HRS) which extend term rewriting to-terms. HRS can describe computations on arbitrary terms with bound variables. We show that rewriting is closely related to undirected equational reasoning , and extend three connuence results from term rewriting to HRS: the critical pair lemma by Knuth and Bendix, connuence of rewriting modulo equations a la Huet, and connuence of orthogonal HRS.
