2. Inequality (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Inequality_(mathematics)

   For instance, to solve the inequality 4x < 2x + 1 ≤ 3x + 2, it is not possible to isolate x in any one part of the inequality through addition or subtraction. Instead, the inequalities must be solved independently, yielding x < ⁠ 1 / 2 ⁠ and x ≥ −1 respectively, which can be combined into the final solution −1 ≤ x < ⁠ 1 / 2 ⁠ .

3. Rearrangement inequality - Wikipedia

   en.wikipedia.org/wiki/Rearrangement_inequality

   Rearrangement inequality. In mathematics, the rearrangement inequality[1] states that for every choice of real numbers and every permutation of the numbers we have. Informally, this means that in these types of sums, the largest sum is achieved by pairing large values with large values, and the smallest sum is achieved by pairing small values ...

4. Inequation - Wikipedia

   en.wikipedia.org/wiki/Inequation

   Inequation. Mathematical statement that two values are not equal. In mathematics, an inequation is a statement that an inequality holds between two values. [1][2] It is usually written in the form of a pair of expressions denoting the values in question, with a relational sign between them indicating the specific inequality relation.

5. Young's inequality for products - Wikipedia

   en.wikipedia.org/wiki/Young's_inequality_for...

   In mathematics, Young's inequality for products is a mathematical inequality about the product of two numbers. [1] The inequality is named after William Henry Young and should not be confused with Young's convolution inequality. Young's inequality for products can be used to prove Hölder's inequality. It is also widely used to estimate the ...

6. Hölder's inequality - Wikipedia

   en.wikipedia.org/wiki/Hölder's_inequality

   Hölder's inequality. In mathematical analysis, Hölder's inequality, named after Otto Hölder, is a fundamental inequality between integrals and an indispensable tool for the study of Lp spaces. Hölder's inequality — Let (S, Σ, μ) be a measure space and let p, q ∈ [1, ∞] with 1/p + 1/q = 1. Then for all measurable real - or complex ...
