WebInequality 7.5(a) below provides an easy proof that Lp(m)is closed under addition. Soon we will prove Minkowski’s inequality (7.14), which provides an important improvement of 7.5(a) when p 1 but is more complicated to prove. 7.5 Lp(m) is a vector space Suppose (X,S,m) is a measure space and 0 < p < ¥. Then Web(1.1). Furthermore, this new inequality includes two other interesting variants of Holder's inequality, the Gagliardo inequality [Gagliardo (1958)] and the Loomis-Whitney inequality [Loomis and Whitney (1949)]. Although these inequalities were only proved for Lebesgue measure, they hold true for arbi-trary product measures.

In probabilistic notation, Jensen’s inequality tells us that (E[f])2 ≤ E[f2], for any f ∈ L1(µ) … WebThe rst thing to note is Young’s inequality is a far-reaching generalization of Cauchy’s inequality.

Proof of Holder

In mathematical analysis, Hölder's inequality, named after Otto Hölder, is a fundamental inequality between integrals and an indispensable tool for the study of L spaces. The numbers p and q above are said to be Hölder conjugates of each other. The special case p = q = 2 gives a form of the Cauchy–Schwarz … See more Conventions The brief statement of Hölder's inequality uses some conventions. • In the definition of Hölder conjugates, 1/∞ means zero. • If p, q ∈ [1, ∞), then f p and g q stand for the … See more Statement Assume that r ∈ (0, ∞] and p1, ..., pn ∈ (0, ∞] such that See more Two functions Assume that p ∈ (1, ∞) and that the measure space (S, Σ, μ) satisfies μ(S) > 0. Then for all measurable real- or complex-valued functions f … See more Hölder inequality can be used to define statistical dissimilarity measures between probability distributions. Those Hölder divergences are projective: They do not depend on the … See more For the following cases assume that p and q are in the open interval (1,∞) with 1/p + 1/q = 1. Counting measure See more Statement Assume that 1 ≤ p < ∞ and let q denote the Hölder conjugate. Then for every f ∈ L (μ), where max indicates that there actually is a g maximizing the … See more It was observed by Aczél and Beckenbach that Hölder's inequality can be put in a more symmetric form, at the price of introducing an extra vector (or function): Let See more Webof inequality they measure, their upper limits,2 and their computational formulae. The two standardized entropy indices and the Lieberson index measure no-null-category inequality or, if null categories are included, ANONC inequality.

Finite measure spaces. If the measure of the space X is ﬁnite, then there are inclusion relations between Lp spaces. To exclude trivialities, we will assume throughout that 0 < µ(X) < ∞.

"WebLike Hölder's inequality, the Minkowski inequality can be specialized to sequences and vectors by using the counting measure : for all real (or complex) numbers and where is the cardinality of (the number of elements in ). The inequality is named after the German mathematician Hermann Minkowski. Proof [ edit] " - Counting measure holders inequality
