WebHere the forcing argument uses a model of set theory as an input (or the syntactic assumption of consistency of that theory, which is not essentially different from assuming a model). $\endgroup$ – T..

The basic concepts of set theory are fairly easy to understand and appear to be self-evident. However, despite its apparent simplicity, set theory turns out to be a very sophisticated subject.

Webmodel theory, set theory and order theory. Then we introduce the concept of a forcing poset and a generic lter over a poset, and explain how to construct the generic extension of a model. After verifying that generic extensions are models of set theory, we use the technique to verify both directions of the independence of the continuum hypothesis. toy350190WebThe author’s other chapter in this volume, \Set Theory from Cantor to Cohen" (henceforth referred to as CC for convenience), had presented the historical de-velopment of set theory through to the creation of the method of forcing.

A statement is consistent with a given family of axioms if it cannot be disproven on the basis of those axioms, and independent of them if it can be neither proven nor disproven.

The intersection of the grounds is the mantle, an inner model of ZFC which enjoys many nice properties. Fuchs, Hamkins, and Reitz showed that the mantle is highly malleable. Namely, they showed that every model of set theory is the mantle of a bigger, better universe of sets. toy360770
