N2 - Nominal rewriting was introduced as an extension of first-order term rewriting by a binding mechanism based on the nominal approach. A distinctive feature of nominal rewriting is that α -equivalence is not implicitly dealt with at the meta-level but explicitly dealt with at the object-level. In this paper, we introduce the notion of strong commutation modulo α -equivalence and give a sufficient condition for it. Using the condition, we present a new criterion for confluence modulo α -equivalence (on ground terms) of possibly non-terminating left-linear nominal rewriting systems.
