【 摘 要 】

We explicitly compute examples of sheaves over the projectivization of the spectrum of the cohomology of sl(2). In particular, we compute ker circle minus(M) for every indecomposable M and we compute. J(i) (M) when M is an indecomposable Weyl module and i not equal p. We also give a brief review of the classification of sl(2)-modules and of the general theory of such sheaves in the case of a restricted Lie algebra. (c) 2014 Elsevier Inc. All rights reserved.
