PERR is an annual international workshop dedicated to the formal verification of program equivalence and related relational problems. It is the 6th in a series of meetings that bring together researchers from different areas interested in equivalence and related questions. PERR 2026 will be a workshop at FLOC 2026, and a satellite event to CAV 2026.

This is an informal workshop that welcomes work in progress, overviews of more extensive work, programmatic or position papers and tool presentations.
