Monoidal categorification from alternating snakes
Matheus Brito, Vyjayanthi Chari
In a recent paper, the authors introduced the notion of an alternating snake and a corresponding family of finite dimensional modules for the quantum affine algebra associated to $…

On dominant --weights and maps between Weyl modules for quantum affine
Matheus Brito, Vyjayanthi Chari
We determine the set of dominant --weights in the Weyl (or standard) modules for quantum affine . We then prove that the space of homomorphisms between standard modules…

Alternating snake modules and a determinantal formula
Matheus Brito, Vyjayanthi Chari
We introduce a family of modules for the quantum affine algebra which include as very special cases both the snake modules and the modules arising from a monoidal categorification…
