Third Cohomology and Fusion Categories
Alexei Davydov, Darren Simmons
It was observed recently that for a fixed finite group , the set of all Drinfeld centres of twisted by 3-cocycles form a group, the so-called group of modular extensions (of…

On Lagrangian algebras in group-theoretical braided fusion categories
Alexei Davydov, Darren Simmons
We describe Lagrangian algebras in twisted Drinfeld centres for finite groups. Using the full centre construction, we establish a 1-1 correspondence between Lagrangian algebras and…
