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.

NettetThe celebrated Hölder inequality is one of the most important inequalities in mathematics and statistics. It is applied widely in dealing with many problems from social science, management science, and natural science. 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. Share Cite Follow edited May 3, 2024 at 4:08

Nettet27. mar. 2015 · The Hölder inequality (like the Cauchy-Schwarz inequality) becomes an equality in the special case where x, y are scalar multiples of each other. Therefore, the left hand side achieves the maximum value ‖ x ‖ q when y is any scalar multiple of x satisfying ‖ y ‖ q / ( q − 1) ≤ 1, and this gives the desired result:

But Hölder's inequality requires u ∈ Lp(U), v ∈ Lq(U). Instead, this problem has u ∈ C0, β(U) ∩ C0, 1(U). The textbook gives the definition of ‖u‖C0 γ ( ˉU): = ‖u‖C ( ˉU) + [u]C0 γ ( ˉU) = sup x ∈ U u(x) + sup x y ∈ U x ≠ y { u(x) − u(y) x − y γ }
