We present a proposal of specification and proof of liveness properties in B event systems under fairness assumptions. We give proof obligations in order to prove basic progress properties in B event systems under two types of assumptions: minimal progress and weak fairness. We define proof obligations in terms of weakest preconditions, which allow us to prove basic liveness properties as usual B proof obligations. We suggest the use of unity “Leads To” operator to specify more general liveness properties. In this way, we integrate the unity logic in the specification and proof of B event systems.
