The reducible Specht modules for the Hecke algebra
Matthew Fayers, Sinead Lyle
The reducible Specht modules for the Hecke algebra have been classified except when . We prove one half of a conjecture which we…

Large dimensional homomorphism spaces between Weyl modules and Specht modules
Sinead Lyle
We give a family of pairs of Weyl modules for which the corresponding homomorphism space is at least 2-dimensional. Using this result we show that for fixed parameters and $p…

On homomorphisms indexed by semistandard tableaux
Sinead Lyle
We study the homomorphism spaces between Specht modules for the Hecke algebras $\h$ of type . We prove a cellular analogue of the kernel intersection theorem and a -analogue…
