Every crowded pseudocompact ccc space is resolvable

We prove that every pseudocompact crowed ccc space is c-resolvable. This gives a partial answer to problems posed by Comfort and Garćıa-Ferriera, and Juhász, Soukup and Szentmiklóssy.

CCC - The Casl Consistency Checker

We introduce the Casl Consistency Checker (CCC), a tool that supports consistency proofs in the algebraic specification language Casl. CCC is a faithful implementation of a previously described consistency calculus. Its system architecture combines flexibility with correctness ensured by encapsulation in a type system. CCC offers tactics, tactical combinators, forward and backward proof, and a ...

Ideals without CCC

Let I be an ideal of subsets of a Polish space X, containing all singletons and possessing a Borel basis. Assuming that I does not satisfy ccc, we consider the following conditions (B), (M) and (D). Condition (B) states that there is a disjoint family F ⊆ P (X) of size c, consisting of Borel sets which are not in I . Condition (M) states that there is a Borel function f : X → X with f[{x}] / ∈ ...

Complete Ccc Boolean Algebras

Let B be a complete ccc Boolean algebra and let τs be the topology on B induced by the algebraic convergence of sequences in B. 1. Either there exists a Maharam submeasure on B or every nonempty open set in (B, τs) is topologically dense. 2. It is consistent that every weakly distributive complete ccc Boolean algebra carries a strictly positive Maharam submeasure. 3. The topological space (B, τ...
