Bernstein-Gelfand-Gelfand complexes and cohomology of nilpotent groups over ${\mathbb{Z}}_p$ for representations with p-small weights

P. Polo, J. Tilouine

We show that for $p$small highest weight $\lambda$, 1) there is a ${\mathbb{Z}}_p$-integral version of the Bernstein-Gelfand-Gelfand complex, still a direct summand subcomplex of the standard comp…
