Homomorphisms to Hook Specht Modules over Quiver Hecke Algebras of Type C
Martín Forsberg Conde, Berta Hudak
We investigate homomorphisms between Specht modules for level 1 cyclotomic quiver Hecke algebras of affine type C. For hook partitions with a `short leg' or a `short arm', we give…

On Cellularity of Hecke Algebras for Wreath Products
Berta Hudak, Chun-Ju Lai
The (generalized) Hu algebra is a nontrivial quantization of the wreath product between symmetric groups, whose representation theory controls the Hecke algebra of th…
