Quantum affine wreath algebras 

To each symmetric algebra we associate a family of algebras that we call quantum affine
wreath algebras.  The definition of these algebras is motivated by constructions in
Heisenberg categorification.  They can be viewed both as symmetric algebra deformations
of affine Hecke algebras of type A and as quantum deformations of affine wreath
algebras.  Special cases include affine Yokonuma-Hecke algebras, and quantum
deformations of affine zigzag algebras.  This is joint work with Daniele Rosso.
