Query: Homomorphisms between Weyl modules for SL_3(k)   We classify all homomorphisms between Weyl modules for SL_3(k) when k is an
algebraically closed field of characteristic at least three, and show that the
Hom-spaces are all at most one-dimensional. As a corollary we obtain all
homomorphisms between Specht modules for the symmetric group when the labelling
partitions have at most three parts and the prime is at least three. We
conclude by showing how a result of Fayers and Lyle on Hom-spaces for Specht
modules is related to earlier work of Donkin for algebraic groups.
