Holder inequality for double series
NettetConsider the real quantities R, x, p. such that R > 0 and (2x ju,)/x > 0, then (R"-'1 - R-^CR" -1)^0 (4) the equality holding only when R == 1. Hence, R" + R-" > R"-^ + R-^" (5) Since x p. ( + /^) = 2 x y. \ < 2 x , the meaning of (5) is that R" + R"", or R1'^ + ^r-a!, increases with increasing . . (Compare with cosh x). Nettet24. sep. 2024 · For Math Olympiad purposes you just need basic algebra to understand Hölder's inequality, so if you're familiar with means inequalities and Cauchy-Schwarz you're just fine. Anyway, this is Hölder's inequality, as I know it. Let p, q be positive real numbers such that 1 p + 1 q = 1. Also, let a 1, …, a n and b 1, …, b n be nonnegative …

NettetI'll add some details on the Minkowski inequality (this question is the canonical Math.SE reference for the equality cases, but almost all of it concerns Hölder's inequality). Nettet27. aug. 2024 · Prove Hölder's inequality for the case that ∫baf(x)dx = 0 or ∫bag(x)dx = 0. Then prove Hölder's inequality for the case that ∫baf(x)dx = 1 and ∫bag(x)dx = 1. This would be what you wrote in your “Case 1,” using Young's inequality. Finally prove Hölder's inequality for the case that ∫baf(x)dx ≠ 0 and ∫bag(x)dx ≠ 0.
NettetIn analysis, Holder's inequality says that if we have a sequence $p_1, p_2, \ldots, p_n$ of real numbers in $ [1,\infty]$ such that $\sum_ {i=1}^n \frac {1} {p_i} = \frac {1} {r}$, and a … NettetHolder’s inequality¨ Theorem A If u,v ∈ R , u ≥ 0 and v ≥ 0, then uv ≤ up p + vq q and equality holds if up = vq.

NettetWHY HOLDER¨ ’S INEQUALITY SHOULD BE CALLED ROGER’S INEQUALITY 71 This inequality for a1 a2 an 1 is known in literature as Lyapunov’s inequality (cf [19], 21]) and means that the norm in lp-space is logarithmically convex as a function of p. Again, Lyapunov proved it in 1901, i.e., later than Rogers Nettet4. sep. 2024 · So I was thinking about the proof of Hölder's inequality for Lorentz spaces. where the exponents are positive and finite ( q can be infinite, but let's ignore that) and 1 / q = 1 / q 1 + 1 / q 2, 1 / p = 1 / p 1 + 1 / p 2. We all know that a Lorentz function can be characterized in 2 ways:
