WebWe give several Bishop–Gromov relative volume comparisons with integral Ricci curvature which improve the results in Petersen and Wei (Geom Funct Anal 7:1031– 1045, 1997). Using one of these volume comparisons, we derive an estimate for the volume entropy in terms of integral Ricci curvature which substantially improves WebDec 16, 2024 · Only a few studies evaluating the metabolism of vitamin D in patients with hypoparathyroidism (HypoPT) have been performed thus far, and, in particular, they mainly investigated the process of vitamin D activation (specifically, 1α-hydroxylation). This study, therefore, aimed to evaluate the extended spectrum of vitamin D metabolites in patients …
WebJan 6, 2024 · The classical Bishop volume comparison theorem asserts that for a complete noncompact n-dimensional Riemannian manifold with nonnegative Ricci tensor, the volume of the geodesic ball of radius r is no more than the one of the ball of the radius r in the Euclidean space \(\mathbb {R}^n\) and hence it must have at most polynomial … http://library.msri.org/books/Book30/files/zhu.pdf
WebIn geodesic polar coordinates, the volume element can be written as dvol = dr^A!(r)d! where d!is the volume form on the standard Sn−1. In what follows, we will suppress the dependence of A!(r)on!for notational convenience. With these notations, we are now ready to state our main result of this section. Theorem 2.2 (Main comparison theorem).
