Foliated positive scalar curvature

WebMay 30, 2024 · thus a smooth function \(R_g:X\rightarrow {\mathbb {R}}\).Hence, the scalar curvature is the sum of the sectional curvatures of X at the point in question. It is apparent, from this definition, that when \(n>2\) this function should only retain some partial amount of information about the shape of the Riemannian manifold (X, g) or that, in other words, a … WebISBN: 978-981-124-935-8 (hardcover) USD 388.00.
