Summary: Reflexive combinatory logic RCL was introduced by S. N. ArtĂ«mov [Russ. Math. Surv. 59, No. 2, 203–229 (2004); translation from Usp. Mat. Nauk 59, No. 2, 9–36 (2004; Zbl 1074.03029)] as an extension of typed combinatory logic CL\(_{\rightarrow }\) capable to internalize its own derivations of typing judgments. It was designed as a basic theoretical prototype of functional programming languages extended by this kind of self-referential capacity. However, its operational aspects remained to be clarified.
We study reductions for reflexive combinatory logic and prove strong normalization and confluence properties.
