The Pinching or Sandwich Theorem - S.O.S. Math

WebbRegarding the pinching theorems for the Ricci curvature, we have Theorem 1.3 ([15]). Let M3 be a compact Lagrangian submanifold of the nearly K¨ahler S6(1) and assume that all Ricci curvatures Ric satisfy Ric(v) > 53 64. Then M3 is totally geodesic, and thus Ric = 2 on M3. An improved version of Theorem 1.3 was obtained by Anti´c-Djori´c ... WebbPinching Theorem Pinching Theorem Suppose that for all n greater than some integer N, a n ≤ b n ≤ c n. If lim n→∞ a n = lim n→∞ c n = L, then lim n→∞ b n = L. Suppose that b n ≤ a n, ∀n > N for some N. If a n → 0, then b n → 0. Example 3. cosn n → 0, since cosn n ≤ 1 n and 1 n → 0. 2 Some Important Limits 2.1 ... WebbAbstract. We employ the pinching theorem, ensuring that some operators Aadmit any sequence of contractions as an operator diagonal of A, to deduce/improve two recent theorems of Kennedy-Skoufranis and Loreaux-Weiss for conditional expectations onto a masa in the algebra of operators on a Hilbert space. We also get a few results for sums dhl near torrance
