The Settingnalysis. A reason for its wide range of applications might be that Combinatorics is rather a way of thinking than a homogeneous theory, and consequently Combinatorics is quite difficult to define. Nevertheless, let us start with a definition of Combinatorics which will be suitable for our purpose: .

The Axioms of Zermelo–Fraenkel Set Theorydance with the Euclidean model for reason, the ideal foundation consists of a few simple, clear principles, so-called ., on which the rest of knowledge can be built via firm and reliable thoughts free of contradictions. However, at the time it was not clear what assumptions should be made and what o

The Axiom of Choiceords, states that . (., the empty set). The full theory .+., denoted ., is called ...The .—which completes the axiom system of Set Theory and which is in our counting the ninth axiom of .—states as follows:... Informally, every family of non-empty sets has a choice function, or equivalently, every C

Happy Families and Their Relativese combinatorial tools developed in the preceding chapters. The families we investigate—particularly .-families and Ramsey families—will play a key role in understanding the combinatorial properties of Silver and Mathias forcing notions (see Chapter . and Chapter . respectively).
