Abstract

We show a rigidity result for subfactors that are normalized by a representation of a lattice $Γ$ in a higher rank simple Lie group with trivial center into a finite factor. This implies that every subfactor of $LΓ$ which is normalized by the natural copy of $Γ$ is trivial or of finite index.

Simplicity of reduced crossed products

We characterize the simplicity of reduced crossed product C*-algebras in terms of stabilizer subgroups. Specifically, we prove that if $G$ is a countable group and $X$ is a minimal $G$-flow, then the reduced crossed product C*-algebra $\mathrm{C}(X) \times_λG$ is simple if and only if there is a point in $X$ with a C*-simple stabilizer subgroup. Further, these conditions are equivalent to a generic point in $X$ having a C*-simple stabilizer subgroup. We also provide an example demonstrating that this result does not extend to uncountable groups. This completely resolves a question of Ozawa.

$\mathrm{C}^*$-selflessness of vigorous groups

We prove that countable groups which admit a faithful piecewise minimal-extremely-proximal action on the Cantor set are $\mathrm{C}^*$-selfless. In particular, topological full groups of second countable, Hausdorff, minimal, purely infinite, topologically principal, ample groupoids with compact unit spaces are $\mathrm{C}^*$-selfless. Examples include the Higman--Thompson groups and the Brin--Thompson groups.

A computable wandering and tracelike vector for modular orbits in the Bergman space

We construct a function $Φ$ such that the orbit under the representation of PSL(2,Z) is an orthonormal basis for the Bergman space with weight $α=12$. Moreover, we show that $Φ$ is effectively computable as a holomorphic function on the upper half-plane (in the precise sense of computable analysis), by providing an effective procedure. This constructs a wandering and tracelike vector for PSL(2,Z), whose abstract existence was proved by Sir Vaughan Jones in his last paper, where the corresponding construction was left as a problem. The function is built using an orthonormalization and modularization method, and it displays modular reminiscencies, despite not being modular itself. provides a computable implementing vector for the abstract anti-isomorphism between the von Neumann algebra $M_{12}(Γ)$ and its commutant, which is generated, in Rădulescu's sense, by cusp-form Toeplitz operators, while Voiculescu's results provide a random matrix model for $M_{12}(Γ)$.
