Omitting Types in Operator Systems
We show that the class of 1-exact operator systems is not uniformly definable by a sequence of types. We use this fact to show that there is no finitary version of Arveson’s extension theorem. Next, we show that WEP is equivalent to a certain notion of existential closedness for C∗-algebras and use this equivalence to give a simpler proof of Kavruk’s result that WEP is equivalent to the complet...
متن کاملOmitting types and AF algebras
The model theory of metric structures ([?]) was successfully applied to analyze ultrapowers of C*-algebras in [?] and [?]. Since important classes of separable C*-algebras, such as UHF, AF, or nuclear algebras, are not elementary (i.e., not characterized by their theory—see [?, §6.1]), for a moment it seemed that model theoretic methods do not apply to these classes of C*-algebras. We prove res...
متن کاملA New Omitting Types Theorem
An omitting types theorem for countable models of superstable theories containing an infinite set of indiscernibles is proved. Various corollaries and applications are given. 1. One of the most useful ways that the model theorist has for controlling models is to attempt to specify the element types that models realize and omit. In this paper we present an omitting types theorem which seems well...
متن کاملShelah’s Omitting Types Theorem in Excruciating Detail
We aim to prove Shelah’s Omitting Types Theorem for AECs [Sh394, Lemma 8.7] in detail. The proofs in [Bal09, Theorem 14.8] and [MaSh285, Proposition 3.3] are only special cases, with [MaSh285] being a very helpful guide. We’ve introduced a slight generalization (allowing the Mα’s to be different models, rather than just one), but this is standard. Sebastien Vasey initially pointed this result o...
متن کاملOmitting Types in Logic of Metric Structures
This paper is about omitting types in logic of metric structures introduced by Ben Yaacov, Berenstein, Henson and Usvyatsov. While a complete type is omissible in some model of a countable complete theory if and only if it is not principal, this is not true for the incomplete types by a result of Ben Yaacov. We prove that there is no simple test for determining whether a type is omissible in a ...
