Clarkson inequality proof
WebNov 15, 2024 · Such inequalities have been studied previously. See for example , where they were referred to as (p, p ′)-Clarkson inequalities. There is a simple relationship between roundness and Clarkson roundness. Lemma 3.3. Suppose that 1 < p ≤ 2. Then if X has Clarkson roundness p it also has roundness p. Proof.

WebSep 3, 2024 · In this paper, we get analogues of Clarkson–McCarthy inequalities for n-tuples of operators from Schatten ideals \(S^{p}\) when parameters taking values in different regions. Using them, we obtain some generalized Clarkson–McCarthy inequalities for \(l_{q}(S^{p})\) spaces of operators. Moreover, we get some norm inequalities for … WebMar 22, 2013 · proof of Clarkson inequality proof of Clarkson inequality Suppose 2 ≤p <∞ and f,g ∈ Lp 2 ≤ p < ∞ and f, g ∈ L p . By the triangle inequality, we have the following …
In mathematics, Clarkson's inequalities, named after James A. Clarkson, are results in the theory of L spaces. They give bounds for the L -norms of the sum and difference of two measurable functions in L in terms of the L -norms of those functions individually. WebAfter that, Clarkson’s inequalities have been treated a great deal by many authors. These investigations were mostly devoted to various proofs and generalizations of these inequalities for Lp and some other concrete Banach spaces [1,2,4,5,7,8,10– 18,20,24,25]. In particular Koskela [12] extended these inequalities in parameters involved.
WebNote that for p = q ≥ 2 the inequality (1.4) reduces to the Clarkson’s inequality on the left hand side of (1.3). On the other hand, if 2 ≤ p≤ q<+∞, then 1/p+ 1/q= 1 only for p= q= 2, and thus the inequality (1.4) cannot be derived from any Clarkson’s inequalities in Theorem 1.1. The following result is basic for the proof of ...
