The Hall Algebras of Annuli
Benjamin Cooper, Peter Samuelson
We refine and prove the central conjecture of our first paper for annuli with at least two marked intervals on each boundary component by computing the derived Hall algebras of the…

Preprojective Analogue of the Cone Construction
Benjamin Cooper, Joshua Sussan
We formulate a relative, representation theoretic, notion of the algebraic cone construction. This motivates a generalization of the cone corresponding to a preprojective algebra.

Steenrod Structures on Categorified Quantum Groups
Anna Beliakova, Benjamin Cooper
Categorified quantum groups play an increasing role in quantum topology and representation theory. The Steenrod algebra is a fundamental component of algebraic topology. In this pa…
