....abstract domain refinements existing in the literature, Cousot and Cousot s reduced power is probably the less known one. In fact, while for the well known reduced product and disjunctive completion a comprehensive literature is available, ranging from the most theoretical aspects (e.g. see [16, 20, 23, 36]) to applications (e.g. see [13, 21, 23, 29, 41, 51, 62] as far as reduced power is concerned very little has been done after [20] both in theory and in applications. Reduced cardinal power has been introduced by Cousot and Cousot in the very last section of their POPL 79 paper (cf. 20, ....
....A is called a disjunctive abstract domain ( 20] In this case, as recalled in Section 2.2, A = fl(ff(D) is a complete sublattice of D . It is well known since [20] that every abstract domain can be lifted to its disjunctive completion: Examples of disjunctive completions can be found e.g. in [21, 23, 29, 36, 41]. The interest in abstract interpretation based on disjunctive domains is evident: Disjunctive abstract domains allow a precise interpretation for disjunction, i.e. concrete and abstract lub s coincide up 3 See e.g. 52, 53, 54, 55] for some applications of the tensor product in abstract ....

Let us then recall how the disjunctive completion refinement is defined. For more details see [Cousot and Cousot 1979b; Fil e and Ranzato 1998; Giacobazzi and Ranzato 1998]. Here, we only consider the simple case of a concrete domain C which is completely distributive (as any powerset h(X ) i is) For a GC (ff; C ; A; fl) we define the following equivalence relation on (A) For all S ; T A, S T , C fl(S ) C fl(T ) The disjunctive completion IP(A) of A ....
