{\L}ukasz Czajka

TL;DR
This paper proves the confluence of an extended combinatory logic system with Boolean constants, solving a known open problem and formalized in Coq.
Contribution
It introduces and proves confluence for an extension of Combinatory Logic with Boolean constants, addressing a specific open problem.
Findings
Proves confluence of CL-pc^1 system
Formal proof completed in Coq
Solves problem 15 from RTA list
Abstract
We show confluence of a conditional term rewriting system CL-pc, which is an extension of Combinatory Logic by Boolean constants. This solves problem 15 from the RTA list of open problems. The proof has been fully formalised in the Coq proof assistant.
