A dozen problems, questions and conjectures about positive scalar curvature

Research output: Chapter in Book/Report/Conference proceedingChapter


Unlike manifolds with positive sectional and with positive Ricci curvatures which aggregate to modest (roughly) convex islands in the vastness of all Riemannian spaces, the domain {SC > 0} of manifolds with positive scalar curvatures protrudes in all direction as a gigantic octopus or an enormous multi-branched tree. Yet, there are certain rules to the shape of {SC > 0} which limit the spread of this domain but most of these rules remain a guesswork. In the present paper we collect a few "guesses" extracted from a longer article, which is still in preparation: 100 Questions, Problems and Conjectures around Scalar Curvature. Some of these "guesses" are presented as questions and some as conjectures. Our formulation of these conjectures is not supposed to be either most general or most plausible, but rather maximally thought provoking.
