A Game-Theoretic Unital Classification Theorem for -Algebras
Jennifer Pi, Michał Szachniewicz, Mira Tartarotti
We study the complexity of the -equivalence relation on unital -algebras, in the sense of descriptive set theory. We prove that -equivalence is analytic, which in turn…
Free Independence is not definable
William Boulanger, Jakub Curda, Emma Harvey +2
Free independence is an important tool for studying the structure of operator algebras. It is natural to ask from the model-theoretic standpoint whether free independence is captur…
Embeddings into the ultrapower of the Jiang-Su algebra
Ben Bouwen, Jennifer Pi
We study existence of embeddings into ultrapowers of the Jiang-Su algebra and the Razak-Jacelon algebra . More specifically, we show that the cone over a…
Strong convergence to operator-valued semicirculars
David Jekel, Yoonkyeong Lee, Brent Nelson +1
We establish a framework for weak and strong convergence of matrix models to operator-valued semicircular systems parametrized by operator-valued covariance matrices $η= (η_{i,j})_…
Reflective Groupwork for Introductory Proof-Writing Courses
Jennifer Pi, Christopher Davis, Yasmeen Baki +1
We discuss two proof evaluation activities meant to promote the acquisition of learning behaviors of professional mathematics within an introductory undergraduate proof-writing cou…
Quantum Expanders and Quantifier Reduction for Tracial von Neumann Algebras
Ilijas Farah, David Jekel, Jennifer Pi
We provide a complete characterization of theories of tracial von Neumann algebras that admit quantifier elimination. We also show that the theory of a separable tracial von Neuman…
On the First-Order Free Group Factor Alternative
Isaac Goldbring, Jennifer Pi
We investigate the problem of elementary equivalence of the free group factors, that is, do all free group factors share a common first-order theory? We establish…
An Elementary Proof of the Inequality for Conditional Free Entropy
David Jekel, Jennifer Pi
Through the study of large deviations theory for matrix Brownian motion, Biane-Capitaine-Guionnet proved the inequality that relates two analogs of entropy in fr…
Uniformly Super McDuff II Factors
Isaac Goldbring, David Jekel, Srivatsav Kunnawalkam Elayavalli +1
We introduce and study the family of uniformly super McDuff II factors. This family is shown to be closed under elementary equivalence and also coincides with the family of II$…
