Nordic Topology Meeting Thursday, August 27, 10:05 - 10:50 Andy Baker: Fun with Dyer-Lashof operations. The (Kudo-Araki-)Dyer-Lashof operations for E-inifinity ring spectra are well understood. However, for certain purposes the interaction with the Steenrod algebra expressed thorough the Nishida relations is hard to use. I will discuss the interaction with the homology coaction of the dual Steenrod algebra and show how this can be used in calculations.
