Homotopy invariance of positive-scalar-curvature metric spaces for manifolds with the same normal 2-type

About 27 years old · traced to

Let MM and NN be closed dd-manifolds with d≥5d \geq 5 and the same normal 22-type. Assume that both MM and NN admit metrics of positive scalar curvature. Write R+(M)\mathcal{R}^+(M) for the space of Riemannian metrics of positive scalar curvature on MM. Normal 2-type homotopy invariance conjecture. One has a homotopy equivalence

R+(M)≃R+(N).\mathcal{R}^+(M) \simeq \mathcal{R}^+(N).

This claim extends the paper's preceding special cases for spin and non-spin manifolds to arbitrary closed manifolds with the same normal 22-type. Its status is not resolved in the supplied text.
