Abstract
We present a general, abstract method to show confluence of weakly normalizing systems. The technique consists in constructing an interpretation of the source system into a target system which is already confluent. If the interpretation satisfies certain simple conditions, then the source system is confluent. The method has been used implicitly in a number of applications, but does not seem to have been presented so far in its generality. We present, as digressions, two other methods for proving confluence.
This work was carried on with the partial support of E.E.C., Esprit Basic Research Action 3070 FIDE and of Italian C.N.R., P.F.I. “Sistemi informatici e calcolo parallelo”.
