Observation congruence is the equality of the process algebra.
- is stable if has no tau-derivative.
- Derivation of equality:
- If ~~ and both are stable, then = .
- If ~~ then alpha. = alpha.
- = (observation congruence)
- If -> , then =>
with ~~ (and vice versa).
- Preserved under all process operators.
