Drinfeld centers for bicategories
Ehud Meir, Markus Szymik
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 c…

Descent, fields of invariants and generic forms via symmetric monoidal categories
Ehud Meir
Let be a finite dimensional algebraic structure (e.g. an algebra) over a field of characteristic zero. We study forms of by using Deligne's Theory of symmetric monoidal…
