Short stories 1 - Equations anyone?

Equations (in seven tongues) and al-Khwarizmi are the stars of Tower of Babel Episode 8. 

Note from our historian: as Yassine says, al-Khwarizmi gave his name to the word 'algorithm', but the use of an algorithm to solve what we now call quadratic equations dates back to the Mesopotamians c1800 BC.

Equivariant KK-rigidity and lifting cocycle morphism

Mikkel Monkholm
(University of Nebraska at Lincoln)
Abstract

In this talk, I will start by presenting what KK-rigidity means and how I together with Chris Schafhauser have modified it to the dynamical setting for strongly outer actions on classifiable C*-algebras. This includes an application to the uniqueness of the Bernoulli shift on the CAR-algebra and Jiang-Su algebra for torsion-free amenable countable discrete groups. Then I will move towards the machinery leading up to the rigidity theorem, which includes some exposition on the cocycle category and classification of equivariant KK-lifts
