Outer models and genericity

1. Introduction Why is forcing the only known method for constructing outer models of set theory? If V is a standard transitive model of ZFC, then a standard transitive model W of ZFC is an outer model of V if V ⊆ W and V ∩ OR = W ∩ OR. Is every outer model of a given model a generic extension? At one point Solovay conjectured that if 0 # exists, then every real that does not construct 0 # lies...

Stability and stable groups in continuous logic

We develop several aspects of local and global stability in continuous first order logic. In particular, we study type-definable groups and genericity.

Groups, measures, and the NIP

We discuss measures, invariant measures on definable groups, and genericity, often in an NIP (failure of the independence property) environment. We complete the proof of the third author’s conjectures relating definably compact groups G in saturated o-minimal structures to compact Lie groups. We also prove some other structural results about such G, for example the existence of a left invariant...

Definable Subsets in Covering Approximation Spaces

Covering approximation spaces is a class of important generalization of approximation spaces. For a subset X of a covering approximation space (U, C), is X definable or rough? The answer of this question is uncertain, which depends on covering approximation operators endowed on (U, C). Note that there are many various covering approximation operators, which can be endowed on covering approximat...

On an Open Problem for Definable Subsets of Covering Approximation Spaces

Let (U ;D) be a Gr-covering approximation space (U ; C) with covering lower approximation operator D and covering upper approximation operator D. For a subset X of U , this paper investigates the following three conditions: (1)X is a definable subset of (U ;D); (2) X is an inner definable subset of (U ;D); (3) X is an outer definable subset of (U ;D). It is proved that if one of the above three...
