Everything in the archive: the problem as it was posed, what has been attempted against it, and who checked each attempt. The mark down the left of the list says who has looked — a person, a machine, or nobody yet. Human reviews and machine checks are counted separately and are never added together.

What is the S_n -module structure of tildeH_3k-4(NM_k(n)) ?
(i) For every triangulation K of a Witt space with vanishing middle intersection homology GIN(K) ⊂ GIN(C(d,n)). (2.1) (ii) The strong upper bound conjecture holds for arbitrary polyhedral complexes (and even for all regular cell complexes…
Given a finite CW complex X which is not contractible and two ρ-immersed matroids (M, l) and (N, l') such that T_X(M, l) ≃ T_X(N, l'), if there exists a surjective weak map τ: M → N, then τ^# is an isomorphism.
