Vopenka and Hajek showed (in their book "Theory of Semisets") how to get Cohen-style models by (1) starting with a permutation model, (2) forcing over it, and (3) passing to the pure (or well-founded) part. Friedman's book "Fine structure and class forcing" develops forcing over ZF, rather than ZFC, in chapter 2. Although chapter 1 is about fine structure, it is not used in chapter 2.

In set theory and its applications throughout mathematics, a class is a collection of sets (or sometimes other mathematical objects) that can be unambiguously defined by a property that all its members share. The precise definition of "class" depends on foundational context. In work on Zermelo–Fraenkel set theory, the notion of class .

The authors of the theory of semisets are P. Vopénka and P. Hájek. We present here some results (not in the most general form) that are contained in their book “Sets, Semisets, Models” (to. the theory of semisets (see below) Vopěnka’s Alternative Set Theory [ edit ] Specifically, Alternative Set Theory (or AST) may refer to a particular set theory developed in the s and s by Petr .

A philosophical theory is a theory that explains or accounts for a general philosophy or specific branch of philosophy. While any sort of thesis or opinion may be termed a theory, in analytic philosophy it is thought best to reserve the word "theory.

This book on the theory of semisets presents a theory whose universe of discourse extends that of set theory; thus, the new theory admits the existence of certain objects which cannot exist from the point of view of set theory.

Semisets are subclasses of sets, whereas in set theory the comprehension axiom ensures that every subclass of a set is a set, the theory of semisets admits the existence of semisets.

It is a generalization of the classi-cal theory obtained by giving up the assumption "all semisets. Axioms Remark In [1, Section 6] we announced a theory of hyperfinite sets THS.

The theory presented here is a result of further development of the idea; the implementation is very different though and, we believe, much more interesting than the one described in [1]. THS is a first-order theory.
