The Tau-Laws of Fusion
Abstract:
We present complete axiomatizations of weak hypercongruence in the
finite fragment of the fusion calculus, an extension and
simplification of the pi-calculus. We treat both the full fusion
calculus and the subcalculus without mismatch operators. The
axiomatizations are obtained from the laws for hyperequivalence and
adding so called tau-laws. These are similar to the well known
tau-laws for CCS and the pi-calculus, but there is an interesting
difference which highlights an aspect of the higher expressive
power of the fusion calculus.
