A general approach to Heisenberg categorification via wreath product algebras

D Rosso, A Savage - Mathematische Zeitschrift, 2017 - Springer
We associate a monoidal category H _B HB, defined in terms of planar diagrams, to any
graded Frobenius superalgebra B. This category acts naturally on modules over the wreath …

On the definition of Heisenberg category

J Brundan - Algebraic Combinatorics, 2018 - numdam.org
We revisit the definition of the Heisenberg category of central charge k∈ Z. For central
charge− 1, this category was introduced originally by Khovanov, but with some additional …

[HTML][HTML] Degenerate cyclotomic Hecke algebras and higher level Heisenberg categorification

M Mackaay, A Savage - Journal of Algebra, 2018 - Elsevier
We associate a monoidal category H λ to each dominant integral weight λ of sl ˆ p or sl∞.
These categories, defined in terms of planar diagrams, act naturally on categories of …

Quantum Frobenius Heisenberg categorification

J Brundan, A Savage, B Webster - Journal of Pure and Applied Algebra, 2022 - Elsevier
We associate a diagrammatic monoidal category Heis k (A; z, t), which we call the quantum
Frobenius Heisenberg category, to a symmetric Frobenius superalgebra A, a central charge …

Affine wreath product algebras

A Savage - International Mathematics Research Notices, 2020 - academic.oup.com
We study the structure and representation theory of affine wreath product algebras and their
cyclotomic quotients. These algebras, which appear naturally in Heisenberg categorification …

String diagrams and categorification

A Savage - Interactions of Quantum Affine Algebras with Cluster …, 2020 - Springer
These are lecture notes for a mini-course given at the conference Interactions of Quantum
Affine Algebras with Cluster Algebras, Current Algebras, and Categorification in June 2018 …

The elliptic Hall algebra and the deformed Khovanov Heisenberg category

S Cautis, AD Lauda, AM Licata, P Samuelson… - Selecta …, 2018 - Springer
We give an explicit description of the trace, or Hochschild homology, of the quantum
Heisenberg category defined in Licata and Savage (Quantum Topol 4 (2): 125–185, 2013 …

Embedding Deligne's category Rep (St) in the Heisenberg category

S Likeng, A Savage, R Christopher - Quantum Topol, 2021 - ems.press
We define a faithful linear monoidal functor from the partition category, and hence from
Deligne's category Rep. St/, to the additive Karoubi envelope of the Heisenberg category …

[HTML][HTML] A graphical calculus for the Jack inner product on symmetric functions

A Licata, D Rosso, A Savage - Journal of Combinatorial Theory, Series A, 2018 - Elsevier
Starting from a graded Frobenius superalgebra B, we consider a graphical calculus of B-
decorated string diagrams. From this calculus we produce algebras consisting of closed …
