LAURA MANČINSKA (Københavns Universitet)
QUANTUM ENTANGLEMENT, GAMES, AND GRAPH ISOMORPHISMS
Entanglement is one of the key features of quantum mechanics. We will see that nonlocal games provide a mathematical framework for studying entanglement and the advantage that it can offer. We will then take a closer look at graph-isomorphism games&nbs...

QUANTITATIVE K-THEORY, K-HOMOLOGY AND THEIR APPLICATIONS
I will give an introduction to quantitative K-theory, K-homology and their applications. In particular, I will discuss my recent joint work with Rufus Willett on the universal coefficient theorem for nuclear C*-algebras. If time allows, I will also talk about other rece...

AF ALGEBRAS ASSOCIATED TO ORIENTED COMBINATORIAL DATA
One of the remarkable features of the construction of C*-algebras from directed graphs is the characterization of approximate finite dimensionality: the C*-algebra is AF if and only if the graph has no directed cycle. This construction has been generalized to other classes of ori...
MAGNUS GOFFENG (Lunds Universitet)
Connes and Moscovici introduced twisted spectral triples over a decade ago as a way of extending spectral noncommutative geometry of finite spectral dimension to situations where no finitely summable spectral triples exist. While there are attractive...
KONRAD AGUILAR (Pomona College)
BUNCE-DEDDENS ALGEBRAS AS QUANTUM-GROMOV-HAUSDORFF-DISTANCE LIMITS OF CIRCLE ALGEBRAS
We show that Bunce-Deddens algebras, which are AT-algebras, are also limits of circle algebras for Rieffel's quantum Gromov-Hausdorff distance, and moreover, form a continuous family indexed by the Baire space. To this end, we endow Bunce-De...
ANDRZEJ SITARZ (Uniwersytet Jagielloński)
THE RIEMANNIAN GEOMETRY OF A DISCRETIZED CIRCLE AND TORUS
Since the inception of noncommutative geometry, the generalization of Riemannian geometry to the noncommutative setup was a challenge. In this talk, we propose techniques that allow us to provide a complete classification of all linear connections for the minimal noncommutative d...
GUILLERMO CORTIÑAS (Universidad de Buenos Aires)
LEAVITT PATH ALGEBRAS AND THE ALGEBRAIC KIRCHBERG-PHILLIPS PROBLEM
The Kirchberg-Phillips theorem says that unital separable nuclear purely infinite simple C*-algebras in the UCT class are classified by their (topological, C*-algebraic) K-theory and, more generally, that any two separable nuclear purely infinite simple C*-algebras that are KK-is...
FRÉDÉRIC LATRÉMOLIÈRE (University of Denver)
FINITE-DIMENSIONAL APPROXIMATIONS OF SPECTRAL TRIPLES ON QUANTUM TORI
The asymptotic behavior of matrix models, as their dimension grows to infinity, is of common interest in mathematical physics. The formalization of the study of limits of finite-dimensional quantum spaces, endowed with some geometric structure, can be done within the larger framework ...
SERGEY NESHVEYEV (Universitetet i Oslo)
QUANTIZATION OF COMPACT SYMMETRIC SPACES: TWO APPROACHES
I will explain two ways of quantizing compact symmetric spaces. The first is due to Letzter and Kolb, giving explicit generators of the dual coideal. The second is essentially due to Enriquez and Etingof, and relies on cyclotomic Knizhnik-Zamolodchikov equations. Both a...
ADAM DOR-ON (Københavns Universitet)
OPERATOR ALGEBRAS OF SUBPRODUCT SYSTEMS BY EXAMPLE
In this talk, we will discuss subproduct systems as introduced by Shalit and Solel in 2009 following a definition given by Bhat and Mukherjee. Subproduct systems were originally defined for the purpose of classifying CP-semigroups, but they also give rise to natura...
