Holder's inequality infinity norm
NettetWhat I want to prove is that the p -norm. ‖ x ‖ p = ( ∑ i = 1 n x i p) 1 / p. is really a norm. Showing that ‖ x ‖ p ≥ 0 being zero if and only if x = 0 was easy. Showing that ‖ k x ‖ p = k ‖ x ‖ p was also easy. The triangle inequality is the thing that is not being easy to show. Indeed, I want to show that: for ...

NettetI know that Holder's inequality is proved using Young's inequality, which is involves convexity. But with bit of algebraic manipulation, we can trivially prove that following for … Hölder's inequality is used to prove the Minkowski inequality, which is the triangle inequalityin the space Lp(μ), and also to establish that Lq(μ)is the dual spaceof Lp(μ)for p∈[1, ∞). Hölder's inequality (in a slightly different form) was first found by Leonard James Rogers (1888). 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), 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 g on S such that g(s) ≠ 0 for μ-almost all s ∈ S, Se mer Conventions The brief statement of Hölder's inequality uses some conventions. • In … 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 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

Following Folland's proof (the inequality after applying Tonelli and Holder), consider ∫ f ( x, y) d ν ( y) as a linear functional (not necessarily bounded) on L q ( μ). If it's bounded, then ∫ f ( x, y) d ν ( y) must be in L p ( μ) and the result is immediate. Otherwise the RHS must be infinity.
