Seminar

Postdoc day, Seminar 1: Twisted homology operations

Higher algebraic structures in algebra, topology and geometry

21 January 13:30 - 14:00

Calista Bernard - University of Minnesota

In the 70s, Fred Cohen and Peter May gave a description of the mod p homology of a free E_n-algebra in terms of certain homology operations, known as Dyer--Lashof operations, and the Browder bracket. I will discuss a framework to generalize these operations to homology with certain twisted coefficient systems and give a description of the homology of a free E_{\infty}-algebra in terms of these operations. I will also give an overview of work in progress on twisted homology operations for E_2-algebras and discuss an application to mixed braid groups.
