  2012 Equivariant Bordism and Labelled Graphs
  Alastair Darby (University of Manchester)
  
  3pm in FRANK ADAMS 2
  Abstract (click to view)

  Results of GKM-theory show that the equivariant cohomology, and other important topological information, of a large class of manifolds with torus action can be combinatorially encoded in a regular labelled graph. We will look at how this may be mimicked in geometric equivariant bordism. We will begin by looking at manifolds with a real torus action and if time permits move on to the more complicated case of unitary toric manifolds.

  2012 The Kervaire invariant
  John Jones (University of Warwick)
  
  3pm in FRANK ADAMS 2
  Abstract (click to view)

  In 2009 Mike Hill, Mike Hopkins and Doug Ravenel proved that the only dimensions in which there are framed manifolds with Kervaire invariant one are 2, 6, 14, 30, 62 and possibly 126. In this talk I will try to highlight the significance of this result for both differential topology and homotopy theory and summarise what is known in the 6 special dimensions.
