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…

A generalization of Carter-Payne homomorphisms
Martín Forsberg Conde
We construct graded homomorphisms between Specht modules of quiver Hecke algebras of type A that differ by an ``-small'' partition-shaped removable set of nodes by expanding on…
