DESCRIPTION:Aras Ergus\, École Polytechnique Fédérale de Lausanne\nFrom
  the (co)homology of a topological group with coefficients in a field to t
 he (dual) Steenrod algebra\, certain algebraic invariants that show up in 
 topology are equipped with a compatible comultiplication that upgrades the
 m to Hopf algebras. One of the main insights of homotopy theory is that al
 gebraic invariants are truncations of objects equipped with homotopy coher
 ent algebraic structures (such as ring spectra)\, so one might hope that t
 he additional "coalgebraic" structures (and their interactions with algebr
 aic ones) can also be lifted to homotopy coherent ones.\n\nIn this talk\, 
 we will give an overview of the theory of such homotopy coherent Hopf alge
 bras and (co)modules over them\, which in particular provides a unifying p
 oint of view on concepts such as (naive) equivariant homotopy theory and T
 hom spectra.
