The rational homotopy type of (n−1)‐connected manifolds of dimension up to 5n−3 Journal of Topology (IF1.582), Pub Date : 2020-03-18, DOI: 10.1112/topo.12133 Diarmuid Crowley, Johannes Nordström
We define the Bianchi–Massey tensor of a topological space to be a linear map , where is a subquotient of determined by the algebra . We then prove that if is a closed ‐connected manifold of dimension at most (and ) then its rational homotopy type is determined by its cohomology algebra and Bianchi–Massey tensor, and that is formal if and only if the Bianchi–Massey tensor vanishes.
