Taken together, these give To see that both inequalities are tight, let be the polar decomposition of , with a partial isometry such that is the support projection of . Nettet1 Answer Sorted by: 1 Let C be a cone and C ∗ = { y: x, y ≥ 0 ∀ x ∈ C } its dual cone. If a point y satisfies x, y ≥ 0 for all extreme rays of C, then it satisfies this inequality for all rays of C. Therefore, we can restrict attention to the extreme rays of C. Each of these rays determines a half-plane { y: x, y ≥ 0 }.

If E is a ﬁnite-dimensional vector space over R or C, for every real number p ≥ 1, the p-norm is indeed a norm.

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 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 … Se mer Two functions Assume that p ∈ (1, ∞) and that the measure space (S, Σ, μ) satisfies μ(S) > 0. Then for all … 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 vector (or function): Let Se mer Conventions The brief statement of Hölder's inequality uses some conventions. • In the definition of Hölder conjugates, 1/∞ means zero. 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.
