An example in the confluence of Algebra, Topology and Geometry: the de Rham complex of a Poisson manifold
Taler(e): Bruno Vallette
(University of Nice, France)
Onsdag den 18. april 2012 kl. 12:05-13:00. Sted: Aud 8. Sprog: engelsk.
This is a lecture in the monthly SYM lecture series aimed to accessible to all members of the center.
Due to the length of the title, there will be no abstract; however we provide the definition of "confluence" (courtesy of Merriam-Webster): "a coming or flowing together, meeting, or gathering at one point <a happy confluence of weather and scenery>"

Towards the classification of outer actions of finite groups on purely infinite algebras
Taler(e): N. Christopher Phillips
(University of Oregon)

UCT Kirchberg algebras (purely infinite simple separable nuclear
C*-algebras satisfying the Universal Coefficient Theorem) are known
to be determined up to isomorphism by K-theoretic invariants. More
recently, a K-theoretic classification has been given for actions of
finite groups on such algebras satisfying the Rokhlin property. We
describe progress toward such a classification under the much less
restrictive condition that the action be pointwise outer, with the
best results being possible when the group is cyclic of prime order.
