  • Positive scalar curvature with point singularities (2026) · Duke Mathematical Journal · doi

    The paper identifies a gap in the understanding of scalar curvature lower bounds for Riemannian L∞-metrics. It notes that prior work has not fully developed a theory for spaces with scalar curvature bounded below. The paper aims to fill this gap by investigating scalar curvature lower bounds for Riemannian L∞-metrics.
