In his celebrated paper in 1976, A. Connes casually remarked that any finite von Neumann algebra ought to be embedded into an ultraproduct of matrix algebras, which is now known as the Connes embedding conjecture or problem. This conjecture became one of the central open problems in the field of operator algebras since E. Kirchberg’s seminal work in 1993 that proves it is equivalent to a variety of other seemingly totally unrelated but important conjectures in the field. Since then, many more…

Synchronous correlation matrices and Connes' embedding conjecture
• Mathematics
• 2015
In a recent paper, the concept of synchronous quantum correlation matrices was introduced and these were shown to correspond to traces on certain C*-algebras. In particular, synchronous correlation
The Connes Embedding Problem: A guided tour
• Isaac Goldbring
• Mathematics
Bulletin of the American Mathematical Society
• 2022
This work introduces all of the background material necessary to understand the proof of the negative solution of the Connes Embedding Problem and outlines two such proofs, one following the “traditional” route that goes via Kirchberg’s QWEP problem inC-algebra theory and Tsirelson's problem in quantum information theory and a second that uses basic ideas from logic.
A negative resolution to Connes’ Embedding Problem and Tsirelson’s problem
Connes’ Embedding Problem is a deep question on approximability of certain tracial von Neumann algebras by finite-dimensional matrix algebras. We survey the connections between operator algebras,

Introduction to Sofic and Hyperlinear Groups and Connes' Embedding Conjecture

This monograph presents some cornerstone results in the study of sofic and hyperlinear groups and the closely related Connes' embedding conjecture. These notions, as well as the proofs of many
Remark on negative solution to the Tsirelson conjecture about quantum correlations
Recently it was proved [arXiv:2001.04383] that a closure of the set of spatial quantum correlations is strictly less than the set of commuting quantum correlations. Thus, the famous Tsirelson

Unbounded expectations to some von Neumann algebras
For any injective von Neumann algebra R and any discrete, countable group G, which acts by *-automorphisms on R, we construct an idempotent mapping of an ultra-weakly dense subspace of B(H) onto the
