We show that a uniformly Euclidean metric with isolated singularity on closed Formula: see text, where Formula: see text or Formula: see text, Formula: see text spin, and nonnegative scalar curvature on the smooth part is flat and extends smoothly over the singularity. This confirms Schoen’s Conjecture in these cases. The novel approach here, which is the key to the proof, is to show that the space has nonnegative synthetic Ricci curvature, i.e., an Formula: see text space. Our result also holds when the singular set consists of a finite union of submanifolds (of possibly different dimensions) intersecting transversally under additional assumption on the co-dimension and the location of the singular set.
