Weyl modules for p-singular weights (Q1100280)

Using the ideas from his recent proof of the very strong linkage principle [J. Algebra 113, No.1, 71-80 (1988)], the author generalizes a theorem of the reviewer's concerning certain composition factors in Weyl modules. He also proves the existence of related homomorphisms between Weyl modules, and in the case where the difference between the two highest weights in question is a multiple of a simple root, he obtains (generically) a formula for the character of the image of such a homomorphism.
