DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYC-NCG/14/"
 >Non-commutative Poincaré Duality of the irrational rotation algebra</a>\
 nby Anna Duwenig (University of Wollongong) as part of Noncommutative geom
 etry in NYC\n\n\nAbstract\nThe irrational rotation algebra is known to be 
 self-dual in a KK-theoretic sense. The required K-homology fundamental cla
 ss was constructed by Connes out of the Dolbeault operator on the 2-torus\
 , but there has not been an explicit description of the dual element. In t
 his talk\, I will geometrically construct that K-theory class by using a p
 air of transverse Kronecker flows on the 2-torus. This is based on joint w
 ork with my PhD advisor\, Heath Emerson.\n
