Extend finite-generation of cohomology to arbitrary Noetherian coefficient rings

Establish whether the cohomology algebra H*(G;k) of a locally finite Artinian group G is finitely generated as a k-algebra for every commutative Noetherian ring k, extending the established result for coefficients in the field F_p.

Background

The paper proves that for a locally finite Artinian group G, the mod-p cohomology ring H*(G;F_p) is a finitely generated F_p-algebra. The authors then identify the analogous statement over an arbitrary commutative Noetherian coefficient ring as unresolved.

The question concerns whether the finite-generation property depends on using a field of characteristic p or persists for all commutative Noetherian base rings. The authors indicate that they expect the result to remain true in this broader setting, but do not establish it.

References

We do not know whether the latter result remains true for an arbitrary Noetherian base ring, although we expect this to be the case.
