Haagerup property is named after Uffe Haagerup and it can be considered a property of groups that strongly negates Kazhdan's property (T). The Haagerup property is common in a lot of mathematical fields. This includes harmonic analysis, representation theory, operator K-theory, geometric group theory. We hope you have the necessary base to answer a few questions.
