Masterclass Applications of the UCT for C*-algebras


Applications of the UCT for C*-algebras

University of Copenhagen
October 2nd to October 6th, 2017

This masterclass will focus on KK-theory and the Universal Coefficient Theorem, with a special regard towards applications to the structure and classification theory of nuclear C*-algebras. Further topics, such as equivariant extensions of KK-theory for C*-algebras over topological spaces or with group actions, will also be explored.


Last lecture series Alain Connes @ CdF

Last Thursday the last lecture series of Alain Connes at Collège de France has started. It will treat two topics, entitled:

There was an overwhelming interest for the first lecture, which has also been recorded and can be viewed here.

Postdoc Quantum Geometry in Nijmegen

A postdoctoral position in quantum gravity and quantum geometry will be available at the Institute for Mathematics, Astrophysics and Particle Physics (IMAPP) of the Radboud University, starting in autumn of 2017. The successful applicant will become part of the research program “Quantum gravity and the search for quantum spacetime”, a collaboration of high-energy theorists and mathematical physicists, sponsored by the Dutch Foundation for Fundamental Research on Matter (FOM).

Applicants should have a background in quantum gravity or related areas, and an active interest in contributing to the consortium’s research in nonperturbative quantum gravity, which focuses on causal dynamical triangulations, renormalization group methods and noncommutative geometry. The appointment will be for two years. The deadline for applications is December 15, 2016. See for more information and how to apply.

KK-theory, Gauge Theory and Topological Phases, School+Workshop

KK-theory, Gauge Theory and Topological Phases School – Workshop
from 27 Feb 2017 through 10 Mar 2017

Lorentz Center Leiden

Scientific organizers:

Alan Carey (Canberra, Australia)
Steve Rosenberg (Boston, MA, USA)
Walter van Suijlekom (Nijmegen, The Netherlands)

This is a school and workshop on new developments in Kasparov theory (also referred to as KK-theory) motivated by applications to gauge theory and topological phases of matter.

The school is intended for PhD-students and postdocs working on KK-theory and/or its applications to physics. This includes young scientists who work on gauge theory or on topological phases with a strong mathematical background, and who want to learn the novel approach to these fields that KK-theory has in stock. Moreover, it is an opportunity for more senior people who are in related fields and want to learn KK-theory.

The workshop is intended for scientists working in the field and also in topological phases of matter, and particularly for the participants of the preceding school. It will attract leading experts from all parts of the world, but will also function as a platform for talented young scientists.

Summer School “Coarse Index Theory”, September 26-30, 2016, Freiburg

Topic:    Index theory is a prime example of fruitful interaction between analysis, geometry, topology and operator algebras.

The index is associated to a global differential operator and is computed from the set of solutions of the associated differential equation. It turns out, however, that the index has remarkable stability properties and can often be computed a priori without solving the differential equation. This uses index theorems and the underlying topology. On the other hand, the most interesting operators are tied to the geometry and the geometry determines the set of solutions. The most powerful implementations of this idea that the relevant operators lie in operator algebras which are specific to the situation at hand. The indices are then naturally defined as elements in K-theory groups of these operator algebras.

It turns out that a particularly useful setup uses the ideas of “coarse  geometry”. The basic idea is to study (non-compact) metric spaces; but  considering only their large scale features. A lot of this can be captured  in appropriately associated C*-algebras; the coarse C*-algebras of the space (often called Roe algebra). This tool also applies to compact spaces, by passing first to their universal covering.

The corresponding manifestation of index theory in this context is “coarse   index theory” or “large scale index theory” and has many interesting  properties and applications.

The summer school will explain the relevant general background in index theory, operator algebras; and then focus on large scale geometry and index theory and its numerous applications.

Program: There will be lecture series by

  • John Roe: Coarse geometry and index theory
  • Thomas Schick: (Secondary) Coarse index and applications
  • Rudolf Zeidler: K-theory of C*-algebras

along with daily exercise and discussion sessions in the afternoon.

Schedule: Preliminary schedule

Funding: As a general rule, you are supposed to arrive with your own funding but there are also some limited funds available.

Contact: Please send an informal email to enroll until September 1, 2016, latest, to Mrs. Ursula Wöske,

Organizer: Nadine Große

Speakers: John Roe, Thomas Schick, Rudolf Zeidler
