Inequality: An inequality is a mathematical expression concerning the relative size of two terms. These come in five kinds; For example, 4 is greater than 3, so either; 4>3 3<4 are true statements. [100%] 2023-02-21 [Mathematics]
Inequality (mathematics): In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size. (Mathematics) [100%] 2023-12-04 [Inequalities] [Elementary algebra]...
Inequality: A relation connecting two real numbers $ a _ {1} $ and $ a _ {2} $ by one of the symbols $ $( greater than), $ \geq $( greater than or equal to), $ \neq $( unequal to), that is, $$ a _ {1} a _ {2} ,\ \ a _ {1 ... (Mathematics) [100%] 2023-12-31
Jackson inequality: An inequality estimating the rate of decrease of the best approximation error of a function by trigonometric or algebraic polynomials in dependence on its differentiability and finite-difference properties. Let $ f $ be a $ 2 \pi $- periodic continuous function on the ... (Mathematics) [70%] 2023-10-21
Bonnesen inequality: One of the more precise forms of the isoperimetric inequality for convex domains in the plane. Let $K$ be a convex domain in the plane, let $r$ be the radius of the largest circle which can be inserted in $K ... (Mathematics) [70%] 2023-10-18
Favard inequality: The inequality $$ \tag{* } \| x \| _ {C [ 0, 2 \pi ] } \leq \ M K _ {r} n ^ {-r} ,\ \ r = 1, 2 \dots $$ where $$ K _ {r} = \ { \frac{4} \pi } \sum _ {k = 0 } ^ \infty (- 1) ^ {k ( r + 1) } ( 2k + 1) ^ {- r - 1 ... (Mathematics) [70%] 2023-12-17
Sobolev inequality: In mathematics, there is in mathematical analysis a class of Sobolev inequalities, relating norms including those of Sobolev spaces. These are used to prove the Sobolev embedding theorem, giving inclusions between certain Sobolev spaces, and the Rellich–Kondrachov theorem showing ...

Triangle inequality: In mathematics, the triangle inequality states that for any triangle, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side. This statement permits the inclusion of degenerate triangles ...

Bogolyubov inequality: in statistical mechanics Bogolyubov's inequality for the free-energy functional is an inequality that gives rise to a variational principle of statistical mechanics.

Poincaré inequality: Let $f\in W^1_p(\mathbb R^n)$, $1\leqslant p < n$ and $p^* = \frac{np}{n-p}$ then the following inequality holds \begin{equation}\label{eq:1} \Bigl(\int\limits_{B}|f(x)-f_B|^{p^*}\,dx\Bigr)^{\frac{1 ... (Mathematics) [70%] 2023-10-24
