NettetProposition 1.6 (Convergences Lp implies in probability). Consider a sequence of random variables (Xn: n 2 N) such that limn Xn = X in Lp, then limn Xn = X in probability. Proof. Let e > 0, then from the Markov’s inequality applied to random variable jXn Xjp, we have PfjXn Xj> eg6 EjXn Xj p e. Example 1.7 (Convergence in probability doesn’t ... Nettetwhere (a) holds by the assumption f ( E [ X]) = E [ f ( X)]; (b) holds by Jensen's inequality applied to the conditional expectations; (c) holds by strict convexity. Hence, f ( m) > f ( m), a contradiction. Cases 1 and 2 together imply that P [ X > m] = 0. Similarly it can be shown that P [ X < m] = 0.

Nettet20. nov. 2024 · This paper presents variants of the Holder inequality for integrals of functions (as well as for sums of real numbers) and its inverses. In these contexts, all possible transliterations and some extensions to more than two functions are also mentioned. Type Research Article Information Hölder's inequality is used to prove the Minkowski inequality, which is the triangle inequality in the space L p (μ), and also to establish that L q (μ) is the dual space of L p (μ) for p ∈ [1, ∞). Hölder's inequality (in a slightly different form) was first found by Leonard James Rogers . Se mer 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 … Se mer For the following cases assume that p and q are in the open interval (1,∞) with 1/p + 1/q = 1. Counting measure For the n-dimensional Se mer Statement Assume that r ∈ (0, ∞] and p1, ..., pn ∈ (0, ∞] such that $${\displaystyle \sum _{k=1}^{n}{\frac {1}{p_{k}}}={\frac {1}{r}}}$$ where 1/∞ is interpreted as 0 in this equation. Then for all … Se mer 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 (possibly infinite) expressions Se mer Statement Assume that 1 ≤ p < ∞ and let q denote the Hölder conjugate. Then for every f ∈ L (μ), Se mer 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 and … Se mer 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 … Se mer Nettet11. jun. 2024 · Holder's inequality in the case of L 1 and L ∞ norm. due to Holder's inequality.

Nettet14. mar. 2024 · To see that the geometric intuition of Young's and Hölder's inequalities are somewhat different, we can look at p = q = 2: In that case, Young's inequality is just the standard AM-GM inequality for two variables. This inequality can be interpreted geometrically. Although here one can also view this as "projection only shortens", the … Nettet17. des. 2024 · What I am confused is the this bolden part: From Jensen's inequality, ∫ h d ν = ( ∫ h p d ν) 1 p where ν is a probability measure, and h is any ν -measurable function. The proof I know of requires h to be integrable, or at least ∫ h d ν &lt; ∞. Supposing this condition is required. If we proceed the proof, we need to first show ∫ h g d ν &lt; ∞
