Abstract
Consider a compact manifold (with or without boundary) of dimension . Positive -intermediate curvature interpolates between positive Ricci curvature () and positive scalar curvature (), and it is obstructed on partial tori . Given Riemannian metrics on with positive -intermediate curvature and -positive difference of second fundamental forms we show that there exists a smooth family of Riemannian metrics with positive -intermediate curvature interpolating between and . Moreover, we apply this result to prove a non-existence result for partial torical bands with positive -intermediate curvature and strictly -convex boundaries.
