Propriétés de relèvement pour les *-algèbres : du local au global ?

Explore the intricacies of lifting properties in C*-algebras in this advanced mathematics lecture. Delve into the central question of whether the local lifting property (LLP) of a C*-algebra implies the global lifting property (LP). Examine Kirchberg's findings related to the Connes embedding problem and its implications. Discover new characterizations of the lifting property for a C*-algebra A, focusing on its maximal tensor product with the full C*-algebra of the free group F_∞. Learn about the recent construction of a non-exact C*-algebra possessing both LLP and WEP. Investigate the potential implication of LLP implying LP for a WEP C*-algebra, and understand the equivalent condition in terms of tensor products. Join Gilles Pisier from Sorbonne Université and Texas A&M University as he presents this complex topic at the forefront of functional analysis and operator algebra research.
