Title: The Haagerup property via Jones' actions

Abstract: A decade ago, Vaughan Jones developed a powerful technology for constructing representations of discrete groups. We will discuss applications of this technology to proving the Haagerup property. We will see that the simple and analytic proof by Brothier and Jones that Richard Thompson’s groups F and T have the Haagerup property extends to the larger Thompson’s group V. We will then discuss generalisations to other Thompson-like groups.
