Adams operations and symmetries of representation categories
Meir, Ehud; Szymik, Markus (Journal article, 2021)Adams operations are the natural transformations of the representation ring functor on the category of finite groups, and they are one way to describe the usual λ–ring structure on these rings. From the representation-theoretical ... -
Drinfeld centers for bicategories
Meir, Ehud; Szymik, Markus (Journal article; Peer reviewed, 2015)We generalize Drinfeld’s notion of the center of a tensor category to bicategories. In this generality, we present a spectral sequence to compute the basic invariants of Drinfeld centers: the abelian monoid of isomorphism ...
