Hopf categories and the categorification of the Heisenberg algebra via graphical calculus

Elena Gal

We explore the connection between the notion of Hopf category and the categorification of the infinite dimensional Heisenberg algebra via graphical calculus proposed by M.Khovanov.…

A geometric approach to Hall algebras I: Higher Associativity

Adam Gal, Elena Gal

We construct a geometric system from which the Hall algebra can be recovered. This system inherently satisfies higher associativity conditions and thus leads to a categorification…
