WitrynaPseudo-Anosovs of interval type Ethan FARBER, Boston College (2024-04-17) A pseudo-Anosov (pA) is a homeomorphism of a compact connected surface S that, away from a finite set of points, acts locally as a linear map with one expanding and one contracting eigendirection. Ubiquitous yet mysterious, pAs have fascinated low … WitrynaFebruary 21, J.D. Quigley (UO) The motivic Hopf invariant one problem. Abstract: Adams showed in 1960 that the (2n-1)-st homotopy group of the n-sphere contains an element of Hopf invariant one if and only if n=2, 4, or 8. This result has interesting applications in geometry and algebra, e.g. the nonexistence of H-space structures on spheres.
