Polynomial Functors on Pointed Categories
Qimh Richey Xantcha
A classification is provided of functors, in particular polynomial ones, from a category with a zero object in which every object is a finite sum of copies of a generating object,…

Centers of partly (anti-)commutative quiver algebras and finite generation of the Hochschild cohomology ring
Elin Gawell, Qimh Richey Xantcha
A partly (anti-)commutative quiver algebra is a quiver algebra bound by an (anti-)commutativity ideal, that is, a quadratic ideal generated by monomials and (anti-)commutativity re…

The Combinatorics of Polynomial Functors
Qimh Richey Xantcha
We propose a new description of Endofunctors of Module Categories, based upon a combinatorial category comprising finite sets and so-called mazes. Polynomial and numerical functors…
