Stefan Bauer (Bielefeld) "Monopoles and stable homotopy"
invariants of differentiable closed 4-manifolds allow for a refinement taking
values in certain equivariant cohomotopy groups. The talk will explain this
construction and how it extends to 4-manifolds bounding rational homology
Le Minh Ha (Leicester) "Sub-Hopf algebras of the Steenrod
algebra and the Singer transfer"
The Singer transfer is an algebraic
gadget which maps into the cohomology of the Steenrod algebra. We investigate
its image using sub-Hopf algebras of the Steenrod algebra and the
"stratification" technique of Quillen and Palmieri. Applications to the
so-called "hit" problem are also
