Abstract

We study some reduced free products of C*-algebras with amalgamations. We give sufficient conditions for the positive cone of the K_0 group to be the largest possible. We also give sufficient conditions for simplicity and uniqueness of trace. We use the later result to give a necessary and sufficient condition for simplicity and uniqueness of trace of the reduced C*-algebras of the Baumslag-Solitar groups BS(m,n).

The Hao-Ng isomorphism theorem for reduced crossed products

We prove the Hao-Ng isomorphism for reduced crossed products by locally compact Hausdorff groups. More precisely, for a non-degenerate $\mathrm{C}^*$-correspondence $X$ and a generalized gauge action $G \curvearrowright X$ by a locally compact Hausdorff group $G$, we prove the commutation ${\mathcal{O}}_{X\rtimes_rG}\cong {\mathcal{O}}_X\rtimes_rG$ of the reduced crossed product with the Cuntz-Pimsner C*-algebra construction. Our proof shows how such commutations with reduced crossed products can follow from more general principles in non-self-adjoint crossed product theory.

Operator Norm Bounds for Multi-leg Matrix Tensors and Applications to Random Matrix Theory

We study the extremal values of multi-leg traces of matrix tensors under operator norm constraints. A graphical representation gives upper and lower bounds expressed as powers of the common tensor-factor dimension. The lower bounds are attained by matrices that permute tensor factors and are exact within this family. We prove the bounds first for two tensor factors and then for an arbitrary number. Leaving some indices uncontracted produces matrices for which we obtain both moment and operator norm bounds; a single choice of coefficient matrices attains the lower bounds for every positive integer moment. We also obtain exact scalar and operator norm maxima in special cases with sufficiently many tensor factors sharing the same cyclic contraction. As an application, the operator norm bounds yield a uniform comparison between Ginibre products and their free circular counterparts with growing matrix coefficients.

On ultraproduct approximations and property (T) factors

We introduce a framework allowing for key aspects of deformation/rigidity theory to be used in the study of continuous model theory of II$_1$ factors. Using this framework, we solve several well-known open problems in the area. For example, we show that the group von Neumann algebras $L(\operatorname{SL}_3(\mathbb Z))$ and $L \mathbb F_2$ are not elementarily equivalent, and we show that the group von Neumann algebra $L\mathbb F_2$ is not pseudomatricial. We also show a Bass-Serre type strong rigidity result in the setting of ultraproducts to provide an infinite family of pairwise non-elementarily equivalent full factors, each of which embeds into an ultraproduct of the hyperfinite II$_1$ factor. Building on previous work of Boutonnet, Chifan and Ioana, we also provide a continuum of pairwise non-elementarily equivalent full factors, which can be taken to be group von Neumann algebras.
