A topological space X is called maximally resolvable if it admits a largest possible family of pairwise disjoint, “maximally dense” subsets. More precisely, if Δ(X) denotes the least among the cardinal numbers of the nonvoid open subsets of X, then X is maximally resolvable if it has isolated points or there exists a family {R α}α < Δ(X) of subsets of X, called a maximal resolution for X, such that ∪{R α | α < Δ(X)} = X, Rγ ∩ Rδ==φ if γ ≠ δ, and, for each a and each nonvoid open subset V of X, the cardinality of R α ∩ V is not less than Δ(X).
